Mylar Type IGBT Snubber Capacitor with Axial Leads for Welding Machine

Short Description:

Capacitor Model: SMJ-TC

Features:

1. Copper nuts electrodes

2. Small physical size and easy installation

3. Mylar tape winding technology

4. Dry resin filling

5. Low Equivalent Series Inductance (ESL) and Equivalent Series Resistance (ESR)

Applications:

1. GTO Snubber

2. Peak Voltage and Peak Current Absorption and Protection for Switching Component in Electronic Equipment

 

Snubber circuits are essential for diodes used in switching circuits. It can save a diode from overvoltage spikes, which may arise during the reverse recovery process.
