Offers High-Temperature Performance

The HT1 Snubber Series high-temperature performance is an alternative to conventional capacitors in applications including high-temperature switching to 150°C, EV/HEV inverters, and industrial power conversion. The HT1 series responds to industry demands for high-temperature capacitors with outstanding peak-current performance surpassing traditional metallized dielectrics.

Our new high temperature polymer, Thermakon™ Technology, can be packaged in other styles.
