Conductive Polymer Aluminum Electrolytic Capacitors
Application Guidelines(SP-Cap)
1. Circuit design
1.1 Prohibited circuits for use
Do not use the SP-Cap with the following circuit.
(1) High-impedance voltage retention circuits
(2) Coupling circuits
(3) Time-constant circuit
(4) Circuit which are greatly affected by leakage current
(5) 2 or more SP-Cap connected serially
1.2 Voltage and polarity
The application of over- voltage and reverse voltage described below can cause increases in leakage current
and short circuits. Applied voltage, refers to the voltage value including the peak value of the transitional
Instantaneous voltage and the peak value of ripple voltage, not just steady line voltage.
Design your circuit so than the peak voltage does not exceed the stipulated voltage.
【Over-Voltage】
Do not apply over-voltage in excess of the rated voltage. Do not apply voltage, which exceeds the full
rated voltage when the SP-Cap receive impulse voltage, instantaneous high voltage, high pulse voltage
etc.
【Reverse-Voltage】
Do not apply reverse-voltage
1.3 Ripple current
Use the SP-Cap within the stipulated permitted ripple current.
When excessive ripple current is applied to the SP-Cap, if causes increases in leakage current and short
circuits due to self-heating.
Even when using the SP-Cap under the permissible ripple current, reverse voltage may occur if the DC bias
voltage is low.
1.4 Leakage current
There is a risk of leakage current characteristics increasing even if the following use environments are within
the stipulated range. However, even if the leakage current increases, the SP-Cap self-repairing function will
reduce the leakage current in most cases when a voltage is applied.
(1) After reflow
(2) Shelf conditions such as high temperature with no load, high temperature high humidity with no load and
sudden temperature changes.
1.5 Temperature
(1) Use at or under the rated (guaranteed) temperature.
Operation at temperatures exceeding specifications causes large changes in the SP-Cap electrical
properties, and deterioration than can potentially lead to failure.
When calculating the operating temperature of the SP-Cap, be sure to include not only the ambient
temperature and internal temperature of the unit, but also radiation from heat generating elements inside
the unit (power transistors, resistors, etc.), and self-heating due to ripple current.
(2) Specified ESR is a value at the time of shipping from factory. ESR may change upon use conditions.
1.6 Failure rate
The majority of failure modes are short circuits or increases in leakage current.
The main factors of failure are mechanical stress, heat stress and electric stress due to re-flow and heat from
the use temperature environment.
Even within the stipulated limits, it is possible to lower the failure rate by reducing use conditions such as
temperature and voltage. Please be sure to have ample margin in your design.
【Expected Failure Rate】
(a) Date based on our reliability tests: 8.2 Fit or less (Based on applied rated voltage at 105 °C)
(b) Market failure rate: 0.13 Fit or less (Based on c=0, Reliability standard : 60 %)
1.7 Mounting area consideration
Isolate the surface of PCB under the mounted SP-Cap.
16-Apr-21
Conductive Polymer Aluminum Electrolytic Capacitors
2. Mounting
2.1 When mounting
(1) Check the SP-Cap ratings (capacitance and voltage) before mounting.
(2) Check the SP-Cap polarity before mounting.
(3) Check the land size for the SP-Cap before mounting.
(4) When using a mounter, if the pressure for mounting is too high, then the current leak may increase,
shortcircuiting may occur, or the SP-Cap may break down or come off.
2.2 Soldering
(1) Reflow soldering
Be performed by one of following methods.
(a) Ambient heat conduction reflow (IR / Hot-air)
Please refer to the page of “Mounting Specifications”.
(b) Vapor phase reflow (but only allowable for CX, CT, SX, ST, GX, LX, LT and HX series).
Please contact Panasonic for details of allowable vapor phase reflow condition.
(2) Wave soldering and dip soldering
Please remind SP-Cap is NOT compatible.
(3) Hand soldering
Excessive force stress to the SP-Cap should be avoided
Conditions
Tip temperature of soldering iron
:350 °C max.
Exposure time
:10 s max.
※ Once removed from the printed circuit board for any reason, please do not use the SP-Cap again.
2.3 Land size
Refer to the land size of “Mounting specifications” for appropriate design dimensions.
Circuit board design requires examination of the most suitable dimensions taking conditions such as circuit
board, parts and reflow into consideration.
2.4 Mechanical stress
Do not apply excessive force to the SP-Cap this can damage the electrodes and badly affect the SP-Cap
mount ability. It can also cause the increase of leakage current, separation of the lead wire and element,
and damage to the SP-Cap body, all of which can badly affect the electrical performance of the SP-Cap.
2.5 Circuit board cleaning
SP-Cap should be cleaned after soldering in accordance with the following conditions.
Temperature
:Less than 60 °C
Time
:Within 5min
Be sure to sufficiently wash and dry (20 min at 100 °C) the board afterward.
【Recommended Cleaning Solvents】
Pine Alpha ST-100S, Clean-thru 750H / 750L / 710M, Aqua Cleaner 210SEP, Sunelec B-12

or deionized water.
(2) The use of ozone depleting cleaning agents are not recommended in the interest of protecting the
environment.
(3) In the case of using ultrasonic cleaning, the terminals may be broken. Therefore, please test before
using in mass production.
3. Usage environment of equipment
Avoid using equipment to which SP-Cap are fi ted in the following environments.
(1) In liquid, such as Water, Oil, Chemicals, or Organic solvent.
(2) In direct sunlight, outdoors, or in dust.
(3) In vapor, such as dew condensation water of resistive element, or water leakage, salty air, or air with
a high concentration corrosive gas, such as Cl2, H2S, NH3, SO2, or NO2.
(4) In an environment where strong static electricity or electromagnetic waves exist.
(5) Mounting or placing heat-generating components or inflammables, such as vinyl-coated wires, near
these SP-Cap.
(6) Sealing or coating of these SP-Cap or a printed circuit board on which these SP-Cap are mounted,
with resin and other material.
(7) Acid or alkaline environments.
(8) Environment subject to excessive vibration and shock.

4. Storage
SP-Cap should be stored in a moisture proof environment. Storage conditions before and after opening the
moisture proof packaging as follows.
(If these conditions are exceeded, the package may absorb moisture and there is a risk of damage to the
exterior due to heat stress during mounting.)
【Environment of Storage】
Temperature
:5 ℃ to 30 ℃
Humidity
:Less than 70 %
Maximum storage term before opening the package
:2 years after manufactured
Maximum storage condition after opening the package
:7 days after opening
SP-Cap should be all used within the storage term after opening the package.
5. Transportation
Take sufficient care during handling because excessive vibration, or shock can cause the reliability of the
SP-Cap to decrease.
6. Emergency procedures
If the SP-Cap is overheated, the resin case may emit smoke. If this occurs, immediately switch off the
unit’s main power supply to stop operation. Keep your face and hands away from the SP-Cap the
temperature may be high enough to cause the SP-Cap to ignite and burn.
7. Discarding
Since SP-Cap are composed of various metals and resins, treat them as industrial waste when arranging
for their disposal.
The precautions in using aluminum electrolytic capacitors follow the "Safety application
guide for the use in fixed aluminum electrolytic capacitors for electronic equipment",
RCR-2367D issued by JEITA in October 2017.
Please refer to the above application guide for details.
