Metallized Film Pulse Capacitors
KEMET's metallized film pulse capacitors for use in power conversion applications
KEMET's pulse capacitors are defined as polypropylene film capacitors for applications that use the stable low dissipation factors required to handle high dv/dt and high ripple currents in power conversion applications. Based on its construction, pulse capacitors have the following advantages:
Single Metallized Film
- Good ripple current performance
- High energy density
- Excellent self-healing
Double Metallized Film
- Higher IRMS and dv/dt performance
- Capable of +125°C
- Good self-healing
Polypropylene Film/Foil
- Highest peak and pulsed current capability
- No self-healing
Features
- R76H 125°C series for automotive AEC-Q200 and harsh environmental applications
- THB: 85°C, 85% RH, 1,000 hours at 700 VAC to 2000 VDC bias
- Highest IRMS capability per volume in the industry
Typical Application
- SMPS silicon-controlled rectifier (SCR and IGBT) and SiC (e.g., MOSFET)
- Commutation circuits, DC link, snubber, resonant converters, and tank circuits
