HVC Capacitor: The Ideal Alternative to Murata High-Voltage Ceramic Capacitors

Murata Manufacturing Co. announced the complete discontinuation of its high-voltage ceramic capacitor product line in the autumn of 2018, citing a shrinking market and lack of profitability. Murata's high-voltage capacitors were renowned for their exceptional performance in limit withstand voltage, high-frequency tolerance, and capacitance stability, and were widely used in medical, inspection, non-destructive testing (NDT), electrostatic, and spraying applications.

In response to this market shift, HVC Capacitor established dedicated production lines in 2018, specifically focusing on replacing Murata's high-voltage lead-type ceramic capacitors and high-voltage bolt-type capacitors (commonly known as "Doorknob Capacitors").

🔄 Replacement Scope

HVC Capacitor serves as a replacement for Murata series including: DHR / DHS / DHK / DHB / DHC. The voltage coverage ranges from 2KV, 3KV, 6KV (medium-high voltage) to 10KV, 12KV, 15KV (high voltage), and up to 20KV to 50KV (ultra-high voltage, bolt-type).
