Type 942C, Polypropylene Capacitors, for High Pulse, Snubber
Very High dV/dt for Snubber Applications
Type 942 round, axial lm capacitors utilize a hybrid section design
of polypropylene lm, metal foils and metallized polypropylene
dielectric to achieve both high peak current as well as superior
rms current ratings. This series is ideal for high pulse operation and
high peak current circuits.
