5 Capacitor Mounting Considerations
use of voltage dividing sharing resistors with
consideration
compensate for voltage imbalances.
Electrical Precautions
Transient recovery voltage may be generated in
the capacitor due to dielectric absorption.
Typical voltage levels are less than 10% of the
rated capacitor voltage. If required, this voltage
can be discharged with a resistor.
The aluminum case of the capacitor has an
indeterminate
terminal. The vinyl sleeve on the capacitor is for
marking and identification purposes and is not
meant to electrically isolate the capacitor.
When designing circuits, consider worst
case capacitor failure modes such as open
or short circuits.
The effects of hot, electrically conductive,
combustible, electrolyte liquid or vapor
escaping from the safety vent should also
be considered.
Circuit Board Design
Avoid wiring pattern runs which pass between
the mounted capacitor and the circuit board.
When dipping into a solder bath, excessive
solder may collect under the capacitor by
capillary action and short circuit the anode and
cathode terminals.
The vinyl sleeve of the capacitor can be
damaged if solder passes through a lead hole
for subsequently processed parts.
Electrically isolate the extra terminal(s) on 4 and
5 pin products from the anode terminal, cathode
terminal, and other circuit paths.
Clearance Requirements
Case mounted pressure relief vents require
sufficient clearance to operate properly.
The minimum clearance is diameter dependent
as follows:
22~35mm diameters: 3mm minimum.
40mm diameters: 5mm minimum.
