Type 947C Polypropylene, DC Link Capacitors
High Current, High Capacitance for Inverter Applications
Type 947C series uses the most advanced metallized lm
technology for long life, high reliability in DC Link applications.
This series delivers high capacitance, high voltage and high ripple
current handling capabilities required for inverters used in wind,
solar, fuel cell applications and more.
