Very High dV/dt for Snubber Applications

Type 942 round, axial film capacitors utilize a hybrid section design

of polypropylene film, 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.
