Vishay Intertechnology, Inc. has 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 less than 25% at 15 kV, which is half

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 kVDC, 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.
