Applications
MKP-IB snubber film capacitors are widely used in IGBT snubber circuits. The peak voltage and peak current can be absorbed for protection when the power switched off.
Features
1. Low self-inductance, small temperature rising
2. Dry-type, solid epoxy resin encapsulation
3. Electronic isolation tape package
4. Small equivalent series resistance (ESR)
