Special care when locating hole positions in p r ox imity to capacitors is recommended. (3) Circuit Board Hole Spacing The c ircuit b oard h oles spacing should match the c apacitor lead wire spacing within the spec ified tolerances. Incorrect spacing can cause excessive lead wire stress d u r ing the inser tion process.

Mar. 2005 – EE18 – Aluminum Electrolytic Capacitor (5)Clearance for Case Mounted Pressure Relief Vents Capacitors with case mounted pressure relief vents require sufficient clearance to allow for proper vent operation. The minimum clearances are dependent on capacitor diameters as follows. f6.3 to f16 mm : 2 mm minimum, f18 to f 35 mm : 3 mm minimum. f40 mm or greater: 5 mm minimum 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 long periods 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 compromised and loss of electrolyte/shortened life can result. (6)Clearance for Seal Mounted Pressure Relief Vents A hole in the circuit board directly under the seal vent location is required to allow proper release of pressure. (7)Wiring Near the Pressure Relief Vent Avoid locating high voltage or high current wiring or circuit board paths above the pressure relief vent. Flammable, high temperature gas exceeding 100° C may be released which could dissolve the wire insulation and ignite. (8)Circuit Board Patterns Under the Capacitor Avoid circuit board runs under the capacitor as electrolyte leakage could cause an electrical short. 2.2 Capacitor Insertion (1) Verify the correct capacitance and rated voltage of the capacitor. (2) Verify the correct polarity of the capacitor before inserting. (3) Verify the correct hole spacing before insertion (land pattern size on chip type) to avoid stress on the terminals. (4) Ensure that the auto insertion equipment lead clinching operation does not stress the capacitor leads where they enter the seal of the capacitor. For chip type capacitors, excessive mounting pressure can cause high leakage current, short circuit, or disconnection. (9)Screw Terminal Capacitor Mounting Do not orient the capacitor with the screw terminal side of the capacitor facing downwards. q Tighten the terminal and mounting bracket screws within the torque range specified in the specification. q 1.6Electrical Isolation of the Capacitor Completely isolate the capacitor as follows. q B etween the cathode and the case (except for axially leaded B types) and between the anode terminal and other circuit paths. q Between the extra mounting terminals (on T types) and the anode terminal, cathode terminal, and other circuit paths. 2.3 Manual Soldering (1) O b s e r v e t e m p e r a t u r e a n d t i m e s o l d e r i n g specifications or do not exceed temperatures of 350°C for 3 seconds or less. (2) If lead wires must be formed to meet terminal board hole spacing, avoid stress on the leadwire where it enters the capacitor seal. (3) If a soldered capacitor must be removed and reinserted, avoid excessive stress to the capacitor leads. (4) Aviod touching the tip of the soldering iron to the capacitor, to prevent melting of the vinyl sleeve. 1.7 Capacitor Sleeve The vinyl sleeve or laminate coating is intended for marking and identification purposes and is not meant to electrically insulate the capacitor. The s l e e v i n g may split or crack if immersed into solvents such as toluene or xylene, and then exposed to high temperatures. Always consider safety when designing equipment and circuits. Plan for worst case failure modes such as short circuits and open circuits which could occur during use. (1)Provide protection circuits and protection devices to allow safe failure modes. (2)Design redundant or secondary circuits where possible to assure continued operation in case of main circuit failure. Design, Specifications are subject to change without notice. Ask factory for technical specifications before purchase and/or use. Whenever a doubt about safety arises from this product, please inform us immediately for technical consulation without fail. Mar. 2005 – EE19 – Aluminum Electrolytic Capacitor 2.4 Flow Soldering (1) Don not immerse the c a p a c i t o r body into the solder bath as excessive internal pressure could result. (2) Observe proper soldering conditions (temperature, time, etc.). Do not exceed the specified limits. (3) Do not allow other parts or components to touch the capacitor during soldering. 2.6 Other Soldering Considerations Rapid temperature rises during the preheat operation and resin bonding operation can cause cracking of the capacitor vinyl sleeve. For heat curing, do not exceed 150°C for a maximum time of 2 minutes. 2.5 Reflow Soldering for Chip Capacitors 2.7 Capacitor Handling after Soldering (1) Avoid movement of the capacitor after soldering to prevent excessive stress on the leadwires where they enter the seal. (2) Do not use the capacitor as a handle when moving the circuit board assembly. (3) Avoid striking the capacitor after assembly to prevent failure due to excessive shock. (1) For reflow, use a thermal conduction system such as infrared radiation (IR) or hot blast. Vapor heat transfer systems (VPS) are not recommended. (2) Observe proper soldering conditions (temperature, time, etc.). Do not exceed the specified limits. (3) Reflow should be performed one time.

The exposed aluminium case is not insulated and could also cause electric shock if touched. (2)Avoid short circuiting the area between the capacitor terminals with conductive materials including liquids such as acids or alkaline solutions. 4. Emergency Procedures (1) I f t h e p r e s s u r e r e l i e f v e n t o f t h e c a p a c i t o r operates, immediately turn off the equipment and disconnect from the power source. This will minimize additional damage caused by the vaporizing electrolyte. (2) Avoid contact with the escaping electrolyte gas which can exceed 100°C 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 Leakage current of a capacitor increases with long storage times. The aluminium oxide film deteriorates as a function of temperature and time. If used without reconditioning, an abnormally high current will be required to restore the oxide film. This current surge could cause the circuit or the capacitor to fail. Capacitor should be reconditioned by applying rated voltage in series with a 1000 Ω , current limiting resistor for a time period of 30 minutes. Snap-in type 2.9 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. V After applying adhesives or coatings, dry thoroughly to prevent residual solvents from being trapped between the capacitor and the circuit board. 5.1 Environmental Conditions (Storage) Capacitors should not be stored in the following environments. (1) Temperature exposure above 35°C or below 15 °C. (2) Direct contact with water, salt water, or oil. (3) High humidity conditions where water could condense on the capacitor. (4) E x p o s u r e t o t o x i c g a s e s s u c h a s h y d r o g e n sulfide,sulfuric acid, nitric acid, chlorine, or ammonia. (5) Exposure to ozone, radiation, or ultraviolet rays.
