Type 940, Polypropylene Capacitors, for Pulse, Snubber
High dV/dt for Snubber Applications
Type 940 round, axial leaded lm capacitors have polypropylene
lm 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
