MKP-IB Snubber Film Capacitor Manufacturer

MKP-IB Snubber Film Capacitor

: http://dentalchairpackage.com/10-pediatric-dental-chair-package.html

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)
