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

Rhea-AI Summary

Vishay Intertechnology (NYSE:VSH) has launched new Class 1 radial-leaded high voltage single layer ceramic disc capacitors designed for industrial and medical applications. The HVCC Class 1 series features superior performance metrics, including capacitance loss of less than 25% at 15 kV (half of Class 2 devices) and dissipation factor below 1.0% at 1 kHz.

The capacitors offer capacitance range from 100 pF to 1 nF, operating at 15 kVDC within temperatures from -30°C to +85°C. These RoHS-compliant devices are specifically engineered for high voltage generators in baggage scanners, medical and industrial X-ray applications, air purifiers, ionizers, and pulsed lasers. Samples and production quantities are currently available with 12-week lead times.

Positive

• New capacitors feature 50% lower capacitance loss compared to Class 2 devices
• Dissipation factor is 0.5% lower than previous solutions, reducing power losses
• Product is already available for sampling and production

Negative

• Extended lead time of 12 weeks for production quantities

Devices Reduce Power Losses in High Voltage Generators for Industrial and Medical Applications

MALVERN, Pa., Sept. 10, 2025 (GLOBE NEWSWIRE) -- 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.
