Aluminum Electrolytic Capacitors (SMD Type)
Application guidelines (SMD Type)
1. Circuit design
1.1 Operating temperature and frequency
Electrical characteristics of the capacitor are likely to change due to variation in temperature and/or frequency.
Circuit designers should take these changes into consideration.
(1) Effects of operating temperature on electrical parameters
At higher temperatures
: Leakage current increases
At lower temperatures
: Hybrid type has smaller capacitance and larger tan δ.
Other aluminum electrolytic capacitors have smaller capacitance, larger tan δ, and larger
impedance as well as equivalent series resistance (ESR).
(2) Effects of frequency on electrical parameters
At higher frequency capacitance and impedance decrease while tanδ increases.
At lower frequency, heat generated by ripple current will rise due to an increase in equivalent series resistance (ESR).
1.2 Operating temperature and life expectancy
(1) Expected life is affected by operating temperature. Generally, each 10 °C reduction in temperature will double the
expected life. Use capacitors at the lowest possible temperature below the upper category temperature.
(2) If operating temperatures exceed the upper category limit, rapid deterioration of electrical parameter will occur and
irreversible damage will result.
Measure not only the ambient temperature but also the surface temperature of the capacitor’s case top, which has effects
of ripple current and radiated heat from power transistors, IC's, and/or resistors.
Avoid placing components, which could conduct heat to the capacitor from the back side of the circuit board.
(3) The formula for calculating expected life is as follows ;
T1-(T2+⊿T)
L2 = L1×2
10
where T1 ≧ T2
L1
: Guaranteed life (h) at temperature, T1 (℃)
L2
: Expected life (h) at temperature, T2 (℃)
T1
: Upper category temperature (℃) *Hybrid type : + temperature rise due to rated ripple current (℃)
T2
: Capacitor's ambient temperature (℃)
⊿T : Temperature rise due to ripple current (°C)
(4) Using the capacitor beyond the rated lifetime will result in short circuit, electrolyte leak, vent open, and large
deterioration of characteristics. The lifetime cannot exceed 15 years due to aging of sealing rubber.
(5) If the capacitor is used in a high temperature condition for a long time, micro cracks may appear on the surface of
sealing rubber, and/or capacitor case exterior may become brownish in color, but the product reliability will not
be influenced.
1.3 Load conditions to avoid
The following load conditions will cause rapid deterioration of capacitor’s electrical characteristics.
In addition, instantaneous heating and gas generation within the capacitor may cause an operation of pressure
relief vent, and that results in electrolyte leaks, explosion and/or fire ignition.
The leaked electrolyte is combustible and electrically conductive.
(1) Reverse voltage
DC capacitors have polarity. Therefore, do not apply the reverse voltage. Find the correct polarity before insertion.
(2) Charge / Discharge applications
General purpose capacitors are not suitable for use in repeating charge/discharge applications.
For such applications, consult a sales representative with actual application condition. Rush current must not
exceed 100 A.
(3) ON-OFF circuit
When using capacitors in circuit where ON-OFF switching is repeated more than 10,000 times a day,
consult a sales representative with actual application condition for an appropriate choice of capacitors.
(4) Over voltage
Do not apply a voltage exceeding the rated voltage. The rated surge voltage can be applied only for a short time.
Make sure that a sum of the DC voltage and the superimposed AC ripple voltage does not exceed the rated voltage.
01-Nov-22
Aluminum Electrolytic Capacitors (SMD Type)
(5) Ripple current
Do not apply ripple currents exceeding the rated value.
Make sure that rated ripple currents superimposed on low DC bias voltages do not cause reverse voltage
conditions. Even if the current is below the rated ripple current, using the capacitor for longer than the rated
lifetime will cause ESR increase and internal generation of heat, which may eventually lead to vent open,
bulging of case/rubber, electrolyte leak, short circuit, explosion, or ignition in the worst case.
1.4 Connections in series or parallel
(1) Capacitors connected in parallel
Because the impedance of the capacitor and PCB’s wiring are very close, various impedance values may cause
unbalanced ripple current loads among parallel capacitors. Combine the same part number and wire them carefully
to minimize the potential risk of an excessive ripple current concentrating to one capacitor of the smallest impedance.
(2) Capacitors connected in series
Voltage being applied to each capacitor must be smaller than the rated voltage. Unbalanced voltages to the series capacitors
may exceed the rated voltage. Voltage-divider resistors considering leakage currents could prevent the over-voltage to
the series capacitors. Conductive polymer hybrid aluminum electrolytic capacitors are not allowed to be connected in series.
1.5 Capacitor mounting considerations
(1) For double sided circuit boards, avoid wiring patterns passing between the mounted capacitor and the circuit board.
When a radial lead type capacitor is dipped into a solder bath, an excess solder may deposit under the capacitor by capillary
action, causing short circuit between anode and cathode terminals. Also, lead holes must be placed with special care
for radial lead type capacitors because laminate on capacitor’s surface may become damaged during flow process.
(2) The pitch between circuit board holes should match the lead wire pitch of the radial lead type capacitors within the
specified tolerances. Unmatched pitch may cause an excessive stress on lead wires during the insertion process and
result in short/open circuit, increased leakage current, or electrolyte leak.
(3) Clearance for case mounted pressure relief
Capacitors with case mounted pressure relief require sufficient clearance to allow for proper pressure relief operation.
The minimum clearance are dependent on capacitor diameters as follows.
(Ø 10 mm to Ø 16 mm: 2 mm minimum, Ø 18 mm: 3 mm minimum)
(4) Wiring near the pressure relief
Avoid locating high voltage or high current wiring or circuit board paths above the pressure relief. Flammable, high temperature
gas that exceeds 100 ℃ may be released which could dissolve the wire insulation and ignite.
(5) Circuit board patterns under the capacitor
Avoid circuit board runs under the capacitor, as an electrical short can occur due to an electrolyte leakage.
(6) Resonant vibration after circuit board’s production may make a heavy load on the capacitor and cause rapid change in
characteristics and/or capacitor’s break.
1.6 Electrical isolation
Electrically isolate the capacitor’s case from cathode terminals, as well as circuit patterns.
1.7 Capacitor coating
The laminate coating is intended for marking and identification purposes and is not meant to electrically insulate the capacitor.
Its color may become brownish in a high-temperature condition, but the marking appearance and electrical characteristics
will not be influenced.
2. Capacitor handling techniques
2.1 Considerations before using
(1) Capacitors have a finite life. Do not reuse or recycle capacitors from used equipment.
(2) Transient recovery voltage may be generated in the capacitor due to dielectric absorption.
If required, this voltage can be discharged with a resistor with a value of about 1 kΩ.
(3) Capacitors stored for a long period of time may exhibit an increase in leakage current.
This can be corrected by gradually applying rated voltage in series with a resistor of approximately 1 kΩ.
(4) If capacitors are dropped, they can be damaged mechanically or electrically. Avoid using dropped capacitors.
(5) Dented or crushed capacitors should not be used.
The seal integrity can be damaged and loss of electrolyte/ shortened life can result.
01-Nov-22
Aluminum Electrolytic Capacitors (SMD Type)
2.2 Capacitor insertion
(1) Verify the correct capacitance and rated voltage of the capacitor.
(2) Verify the correct polarity of the capacitor before insertion.
(3) Verify the correct terminal dimension and land pattern size for surface mount type, or holes’ pitch for radial lead type before
mount to avoid short circuit, stress on the terminals, and/or lack of terminal strength.
(4) Excessive mounting pressure can cause high leakage current, short circuit, or disconnection.
(5) When using a mounter for radial lead type, avoid cutter wear and acute angle of lead-bending with respect to circuit board.
That may create excessive stress and pull the lead to damage the capacitor.
2.3 Reflow soldering (for surface mount type)
(1) Surface-mount type capacitor are exclusively for reflow soldering.
When reflow solder is used an ambient heat condition system such as the simultaneous use of infrared and hot-air
is recommended.
(2) Observe proper soldering conditions (temperature, time, etc.). Do not exceed the specified limits.
If the peak temperature is high or if the heating time is long, it may cause deterioration of the electrical characteristics and
life characteristics.
Recommended soldering condition is a guideline for ensuring the basic characteristics of the components, but not for the
stable soldering conditions. Conditions for proper soldering should be set up according to individual onditions.
・ The Temperature on Capacitor top shall be measured by using thermal couple that is fixed firmly by epoxy glue.
(3) In case of use in 2 times reflow, 2nd reflow must be done when the capacitor’s temperature return back to normal level.
(4) In our recommended reflow condition , the case discoloration and the case swelling might be slightly generated.
But please acknowledge that these two phenomena do not influence the reliability of the product.
(5) The crack on top marking might be occurred by reflow heat stress.
But please acknowledge that it does not influence the reliability of the product.
(6) VPS (Vapor Phase Soldering) reflow can cause significant characteristics change and/ or mounting failure due to
deformation by acute temperature rise.
VPS is acceptable provided that the process does not exceed recommended reflow profile and temperature rise
is less than 3 ℃/sec.
Please contact Panasonic for detailed conditions.
(7) The vibration-proof capacitors of size ø6.3 has support terminals extending from the bottom side to the lead edge.
Then, make sure to find appropriate soldering conditions to form fillet on the support terminals if required for appearance
inspection. However, even if sufficient solder fillets are not observed, the reliability of vibration-proof will not be lowered
because the support terminals on the bottom side enhance the solder joint to PCB.
2.4 Flow soldering (for radial lead type)
(1) Radial lead type capacitors cannot apply to reflow soldering.
(2) Do not immerse the capacitor body into the solder bath as excessive internal pressure could result.
(3) Apply proper soldering conditions (temperature, time, etc.). Do not exceed the specified limits.
(4) Do not allow other parts or components to touch the capacitor during soldering.
2.5 Manual soldering
(1) Apply soldering conditions (temperature and time) based on the specification, or do not exceed temperature
of 350 ℃ for 3 seconds.
(2) If a soldered capacitor must be removed and reinserted, avoid excessive stress on the capacitor leads.
(3) Avoid physical contacts between the tip of the soldering iron and capacitors to prevent capacitor failure.
(4) When bending lead wires of radial type capacitors to match the hole pitch on PCB, avoid applying excessive stress
to the capacitor body.
2.6 Capacitor handling after soldering
(1) Avoid moving the capacitor after soldering to prevent excessive stress on the lead wires where they enter the seal.
The capacitor may break from element portion due to a torque at outer rim, causing a large stress to terminals.
(2) Do not use the capacitor as a handle when moving the circuit board assembly. The total weight of the board would
apply to element portion through terminals, and the capacitor may break.
(3) Avoid striking the capacitor after assembly to prevent failure due to excessive shock. The capacitor may break due to
excessive shock or load above specified range.

Aluminum Electrolytic Capacitors (SMD Type)
2.7 Circuit board cleaning
(1) Circuit boards can be immersed or ultrasonically cleaned using suitable cleaning solvents for up to 5 minutes and
up to 60 °C maximum temperatures. The boards should be thoroughly rinsed and dried.
The use of ozone depleting cleaning agents is not recommended for the purpose of protecting our environment.
【Target solvent】
Pine Alpha ST-100S, Aqua Cleaner 210SEP, Clean-thru 750H / 750L / 710M, Sunelec B-12,
Sunelec B-12, Cold Cleaner P3-375, Techno Cleaner 219, DK Be-clear CW-5790,
Telpene Cleaner EC-7R, Technocare FRW-17 / FRW-1 / FRV-1
(2) Avoid using the following solvent groups unless specifically allowed in the specification ;
(a) Halogenated based solvents : may permeate the seal and cause internal corrosion.
Especially, 1-1-1 trichloroethane must not be used on any aluminum electrolytic capacitors.
(b) Alkaline based solvents
： may dissolve and react to the aluminum case.
(c) Petroleum based solvents
： may deteriorate the sealing rubber.
(d) Xylene
： may deteriorate the sealing rubber.
(e) Acetone
： may erase the markings on the capacitor top.
(3) A thorough drying after cleaning is required to remove residual cleaning solvents that may be trapped between the
capacitor and the circuit board. Avoid drying temperatures, which exceed the upper category temperature of the capacitor.
(4) Monitor the contamination levels of the cleaning solvents during use in terms of electrical conductivity, pH, specific gravity,
and water content. Inside the capacitor may corrode with high density of chlorine.
Control the flux density in the cleaning agent to be less than 2 mass%.
(5) Depending on the cleaning method, the marking on a capacitor may be erased or blurred.
※ Please consult us if you are not certain about acceptable cleaning solvents or cleaning methods.
2.8 Mounting adhesives and coating agents
When using mounting adhesives or coating agents to control humidity, avoid using materials containing halogenated solvents.
Also, avoid the use of chloroprene based polymers.
Cure or dry out the coating agents thoroughly, and do not leave any solvents. Make sure to dry out cleaning agents completely
immediately after washing the circuit board if the capacitors are mounted afterward, so that the solvents are not left under
the capacitor body. Also, leave more than 1/3 of the sealing portion open, and do not cover that portion with any adhesives
or coating.
2.9 Potting and molding
Potting and molding processes cannot be recommended. They have potential risks to change the capacitor’s performance
and reliability due to injection pressure, diffused material into the capacitor, as well as heat accumulation by covered resin.
Also, evaporated electrolyte may remain inside the resin, then turn to liquid, and possibly short circuit PCB patterns.
2.10 Fumigation
In exporting electronic appliances with aluminum electrolytic capacitors, in some cases fumigation treatment using such
halogen compound as methyl bromide is conducted for wooden boxes.
If such boxes are not dried well, the halogen left in the box is dispersed while transported and enters in the capacitors inside.
This possibly causes electrical corrosion of the capacitors. Therefore, after performing fumigation and drying make sure
that no halogen is left. Don’t perform fumigation treatment to the whole electronic appliances packed in a box.
2.11 Flux
If you use a halogen type (Chlorine type, Bromine type, etc.) high-activity flux, please use it after confirmation
in advance, as it may have an impact on performance and reliability of this product due to the residue of the flux.
3. Precautions for using capacitors
3.1 Environmental conditions
Capacitors should not be stored or used in the following environments.
(1) Exposure to temperatures above the upper category or below the lower category temperature of the capacitor.
(2) Direct contact with water, salt water, or oil.
(3) High humidity conditions where water could condense on the capacitor.
(4) Exposure to toxic gases such as hydrogen sulfide, sulfuric acid, nitric acid, chlorine, chlorine compound, bromine,
bromine compound or ammonia.
(5) Exposure to ozone, radiation, or ultraviolet rays.
(6) Vibration and shock conditions exceeding specified requirements.
Even within the specified requirements, a large vibration acceleration may be applied due to resonance,
so be sure to evaluate and confirm with the actual product.
01-Nov-22
Aluminum Electrolytic Capacitors (SMD Type)
3.2 Electrical precautions
(1) Avoid touching the terminals of a capacitor as a possible electric shock could result. The exposed aluminum case
is not insulated and could also cause electric shock if touched.
(2) Avoid short circuiting the capacitor terminals with conductive materials such as acids or alkaline solutions.
(3) Electrical characteristics may largely change if a silicon material with low molecular-weight siloxane is used near the
capacitor.
4. Emergency procedures
(1) If the pressure relief of the capacitor operates, immediately turn off the equipment and disconnect from the power source.
This will minimize an additional damage caused by the vaporizing electrolyte.
(2) Avoid contact with the escaping electrolyte gas, which can exceed 100 ℃ temperatures.
If electrolyte or gas enters the eye, immediately flush the eye with large amounts of water.
If electrolyte or gas is ingested by mouth, gargle with water.
If electrolyte contacts the skin, wash with soap and water.
5. Long term storage
(1) Leakage current of a capacitor tends to increase after a long-term storage due to dielectric dissolution, and very
high current may flow at the first voltage load. However, applying voltage will form the dielectric, and the leakage current will
decrease. Expiration date is 42 months from the outgoing inspection date for part numbers listed below, and it is 12 month
