MALVERN, PA — Vishay Intertechnology, Inc. (NYSE: VSH) announced the release of its new Vishay BCcomponents PTCES series of insulated, surface-mount positive temperature coefficient (PTC) thermistors. The devices are engineered to improve efficiency, reliability, and cost-effectiveness in automotive and industrial power systems.
The PTCES series delivers up to 340 joules of energy handling and supports voltages up to 1200 VDC—performance levels that surpass comparable components by significant margins. According to Vishay, the new thermistors provide as much as 260 percent higher energy handling and 20 percent higher maximum voltage capabilities than competing products, allowing designers to use fewer components while saving board space and reducing overall system costs.
Built for demanding environments, the thermistors offer current limitation and overload protection in AC/DC and DC/DC converters, DC-Link and energy dump circuits, on-board chargers, battery charging equipment, and motor drives. The self-protecting devices are rated to withstand more than 100,000 inrush power cycles and meet AEC-Q200 qualification standards for automotive-grade shock and vibration performance.
Each thermistor features a solder-connected barium titanate ceramic core enclosed in a UL 94 V-0 compliant, self-extinguishing plastic housing that provides insulation up to 3 kVAC. With a low 9.6 mm profile, the RoHS-compliant, halogen-free design supports automated pick-and-place assembly, further reducing production time and cost.
Vishay’s latest thermistor series reinforces the company’s focus on advancing component efficiency and reliability for next-generation automotive and industrial applications.
