940C Datasheet, PDF (1/5 Pages) Cornell Dubilier Electronics – High dV/dt for Snubber Applications

Type 940C, Polypropylene Capacitors, for Pulse, Snubber
High dV/dt for Snubber Applications
Type 940 round, axial leaded film capacitors have polypropylene
film and dual metallized electrodes for both self healing
properties and high peak current carrying capability (dV/dt). This
series features low ESR characteristics, excellent high frequency
and high voltage capabilities.
