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.

Relief Vents
Capacitors with case mounted pressure relief vents
A hole in the circuit board directly under the seal
vent location is required to allow proper release
of pressure.
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.
Avoid circuit board runs under the capacitor as
electrolyte leakage could cause an electrical short.
Do not orient the capacitor with the screw terminal
side of the capacitor facing downwards.
