1.5 Capacitor Mounting Considerations
(1) Double-Sided Circuit Boards
Avoid wiring pattern runs, which pass between the mounted capacitor and the circuit board.
(2) Land/Pad Pattern
The circuit board land / pad pattern size for chip capacitor is specified in the following table.

※The land pattern and size shall be decided in consideration of mountability, solderbility and strength.
(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. (φ10 mm)
(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 ﾟ C 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.
1.6 Electrical Isolation of the capacitor
Completely isolate the capacitor as follows.
ï½¥Between the cathode and the case and between the anode terminal and other circuit paths.
1.7 Capacitor Sleeve
The laminate coating is intended for marking and identification purposes and is not meant to electrically insulate the capacitor.
CAUTION!
Always consider safety when designing equipment and circuits. Plan for the 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.
