Ultra-high Voltage Capacitors


TDK offers ultra-high voltage capacitors for various applications


TDK's UHV and FHV series high voltage ceramic capacitors feature low dissipation and excellent voltage-capacitance characteristics using patented strontium titanate (SrTiO3) for dielectric material. They are epoxy-encapsulated to meet requirements for high voltage applications.

The TSF and GA series are applicable to Gas Insulated Switchgear. TDK’s FD series are molded from resins that provide outstanding insulation and moisture resistance, making them ideal for high-voltage power circuits in electrical power transmission and receiving devices.
