MALVERN, PA — Vishay Intertechnology, Inc. (NYSE: VSH) has introduced a new series of high-voltage ceramic disc capacitors designed to improve efficiency and reliability in demanding industrial and medical applications.
The Vishay Roederstein HVCC Class 1 series capacitors stand out for their ability to maintain stable performance under high voltage while minimizing energy loss. Compared to widely used Class 2 devices, the new capacitors cut capacitance loss in half, registering less than 25 percent at 15 kilovolts. They also deliver a dissipation factor of under 1 percent at 1 kHz—roughly 0.5 percent lower than Class 2 alternatives—reducing power losses in equipment where efficiency is critical.
These technical gains make the components particularly suited for systems that operate under extreme electrical demands. Applications include high-voltage generators used in baggage scanners, medical and industrial X-ray machines, pulsed lasers, and consumer and industrial air purifiers.
The HVCC Class 1 series offers capacitance values ranging from 100 picofarads to 1 nanofarad, with ±10 percent tolerance, and is rated for voltages up to 15 kVDC. The devices function across a temperature range of -30°C to +85°C, ensuring stability in varied environments. Each capacitor consists of a silver-plated ceramic disc with tinned copper-clad steel leads, available in two diameters and lead spacings.
The components are encapsulated in flame-resistant epoxy resin compliant with UL 94 V-0 standards and meet RoHS requirements, aligning with international safety and environmental regulations.
By combining high reliability, lower power losses, and consistent performance, Vishay’s HVCC Class 1 capacitors are positioned to support the growing demand for precision and efficiency in both industrial technologies and advanced medical devices.
