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.
Highlights
- High dV/dt
- High pulse current
- Low inductance
- Self healing
