Vishay Intertechnology Class 1 Radial-Leaded High Voltage Single Layer Ceramic Disc Capacitors Feature Low DC Bias and DF

MALVERN, Pa. - September 10, 2025 - Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of Class 1 radial-leaded high voltage single layer ceramic disc capacitors that deliver a low dissipation factor (DF) and DC bias for industrial and medical applications.

Vishay Roederstein HVCC Class 1 series capacitors feature capacitance loss of < 25 % at 15 kV, which is half that of Class 2 devices. In addition, their < 1.0 % DF at 1 kHz is 0.5 % lower. The result is reduced power losses and high reliability in high voltage generators for baggage scanners, medical and industrial X-ray applications, air purifiers and ionizers, and pulsed lasers.

HVCC Class 1 series devices feature a capacitance range from 100 pF to 1 nF - with standard tolerances of ± 10 % - voltages of 15 kV_DC, and an operating temperature range from -30 °C to +85 °C. The capacitors consist of a silver-plated ceramic disc with tinned copper-clad steel connection leads offering 0.65 mm and 0.80 mm diameters. The RoHS-compliant devices are available with straight leads with spacing of 9.5 mm and 12.5 mm, and feature an encapsulation made of flame-resistant epoxy resin in accordance with UL 94 V-0.

Samples and production quantities of the HVCC Class 1 series are available now, with lead times of 12 weeks.
