Ultra-high Voltage Ceramic Capacitors

Molded Type with Metal Terminals UHV, FHV Series

CLASS 2 HIGH DIELECTRIC

DC. 20 TO 50kV: UHV-1A TO 12A, 221A TO 253A TYPES

DC. 15 TO 50kV: FHV-1AN TO 12AN, 153AN TYPES

TDK UHV and FHV series high voltage ceramic capacitors feature

low dissipation and excellent voltage-capacitance characteristics

using patented strontium titanate for dielectric material. They are

epoxy-encapsulated to meet requirement of high voltage applica-

tions.

FEATURES

•Small size.

• Low dissipation factor.

• Excellent voltage-capacitance characteristics.

• Screw terminals for easy mounting.

• FHV series: High capacitance and low temperature characteri-

stics of capacitance.

APPLICATIONS

High voltage power supplies, laser equipment.
