PTC thermistors save space
Vishay Intertechnology, Inc. launches a new series of insulated, surface-mount inrush current limiting positive temperature coefficient (PTC) thermistors. The Vishay BCcomponents PTCES series devices offer maximum energy handling up to 340 J with high maximum voltages of 1,200 VDC in a compact package, providing increased board-level efficiency and lower costs in automotive and industrial applications.
Vishay said the new PTCES PTC thermistors offer up to 260% higher energy-handling capabilities compared to competing devices, which helps to reduce component count to save board space and lower overall costs. These devices also offer 20% higher maximum voltages than competing devices.
The PTC thermistors provide current limitation and overload protection in AC/DC and DC/DC converters; DC-Link, energy dump, and emergency discharge circuits; on-board chargers and battery charging equipment; and motor drives. They withstand >100,000 inrush power cycles and are AEC-Q200 qualified for shock and vibration, eliminating the need for reinforced mounting adhesives, Vishay said.
The series is comprised of solder-connected homogeneous ceramic PTCs encapsulated in a UL 94 V-0 compliant, self-extinguishing, washable plastic housing with insulation up to 3 kVAC. The devices feature a low profile of 9.6 mm and can be automatically mounted by pick-and-place equipment to reduce placement costs.
The PTC thermistors are RoHS-compliant and halogen-free. Samples and production quantities are available now, with lead times of 10 weeks. Pricing for U.S. delivery starts at $0.90 each in quantities of 1,000. Click here for the datasheet.
