Vishay Intertechnology 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 <25 % at 15kV, which is half that of Class 2 devices. In addition, their <1.0 % DF at 1kHz 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 ionisers, 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 15kVDC, 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 0.65mm and 0.80mm diameters. 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, with lead times of 12 weeks.
