Vishay Intertechnology radial-leaded, high-voltage, single-layer ceramic disc capacitors offer industry-high capacitance of 2 nF

Vishay Intertechnology Inc. has introduced a new series of radial-leaded, high-voltage, single-layer ceramic disc capacitors in compact sizes. The industry’s only such components to deliver high capacitance values of 2 nF, Vishay Roederstein HVCC series capacitors offer guaranteed load life performance of 1,000 h at 125% rated voltage and 105°C. The dissipation factor is less than 1.5%. HVCC series capacitors may offer a qualified and high-performance drop-in replacement for almost all Murata part numbers starting with DHR, for which the company has sent out an official discontinuation notice. Please refer to Vishay’s HVCC series datasheets to verify requirements.

With their high capacitance, the HVCC devices eliminate the need to utilize two 1 nF capacitors in parallel to reach values of 2 nF. For designers, this saves space, reduces assembly costs and increases reliability in high-voltage generators for dental and baggage scanners, medical and industrial X-ray applications, and pulsed lasers.

The devices offer a capacitance range from 100 pF to 2,000 pF — with standard tolerances of ±20% — voltages from 10 kV DC to 15 kV DC, and operate over a temperature range of -30° C to 105° C. HVCC series capacitors are also available with 20 kV DC rated voltage, ±10% tolerance and custom lead styles on request.

The devices consist of a silver-plated ceramic disc with tinned copper-clad steel connection leads offering 0.6 mm and 0.8 mm diameters. The capacitors are available with straight leads with spacing of 9.5 mm and 12.5 mm. The RoHS-compliant components’ encapsulation is made of flame-resistant epoxy resin in accordance with UL 94 V-0.
