Type 940C High dV/dt, Round Polypropylene Film Capacitors
Double Metallized – Axial Leads
Type 940C 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.
