Protection and switching performance optimization
Our snubber film capacitors are designed to protect power electronic components by limiting voltage spikes and controlling switching transients. They play a critical role in improving reliability and extending the lifetime of semiconductors such as IGBTs and SiC devices.
Built for fast switching environments, these capacitors offer low inductance, high pulse capability, and excellent stability under repetitive stress conditions.
Typical applications:
Snubber circuits for IGBT and SiC modules
Voltage spike suppression
Switching transient control
High-frequency power converters

Segmentation to get protection
At CEFEM, using breakthrough technologies is part of our values. Segmented film is one of them.
Segmentation technology replaces the overpressure one.
Our film embeds fuses meaning that when a fault occurs, the outside circuitry will rush through the low resistance path created by the fault.
Consequently, the fault will heat and vaporize surrounding fault site. The amount of gas and the default will be limited to the area where the fault occurre
WHY CHOOSING SEGMENTATION?
- Cheaper and Lighter
- No Maintenance
- Can be cast on in any way possible
- More ecological
