Class 1 radial-leaded high voltage single-layer ceramic disc capacitors feature low DC bias and DF

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 provide capacitance loss of <25% at 15kV, which is half that of Class 2 devices. Also, their <1% DF at 1kHz is 0.5% lower. The result is decreased power losses and high reliability in high voltage generators for baggage scanners, medical and industrial X-ray applications, air purifiers and ionisers, and pulsed lasers.

The series devices feature a capacitance range from 100pF to 1nF, with standard tolerances of ±10%, voltages of 15kVDC, and an operating temperature range from -30C to +85C. The capacitors consist of a silver-plated ceramic disc with tinned copper-clad steel connection leads, offering diameters of 0.65mm and 0.8mm. The RoHS-compliant devices are available with straight leads with spacing of 9.5mm and 12.5mm, 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.
