Vishay Intertechnology, Inc. launches a brand new sequence of insulated, surface-mount inrush present limiting optimistic temperature coefficient (PTC) thermistors. The Vishay BCcomponents PTCES sequence gadgets provide most vitality dealing with as much as 340 J with excessive most voltages of 1,200 VDC in a compact bundle, offering elevated board-level effectivity and decrease prices in automotive and industrial functions.
Vishay mentioned the brand new PTCES PTC thermistors provide as much as 260% greater energy-handling capabilities in comparison with competing gadgets, which helps to scale back element depend to save lots of board area and decrease total prices. These gadgets additionally provide 20% greater most voltages than competing gadgets.
The PTC thermistors present present limitation and overload safety in AC/DC and DC/DC converters; DC-Hyperlink, vitality dump, and emergency discharge circuits; on-board chargers and battery charging tools; and motor drives. They face up to >100,000 inrush energy cycles and are AEC-Q200 certified for shock and vibration, eliminating the necessity for strengthened mounting adhesives, Vishay mentioned.
The sequence is comprised of solder-connected homogeneous ceramic PTCs encapsulated in a UL 94 V-0 compliant, self-extinguishing, washable plastic housing with insulation as much as 3 kVAC. The gadgets function a low profile of 9.6 mm and will be routinely mounted by pick-and-place tools to scale back placement prices.
The PTC thermistors are RoHS-compliant and halogen-free. Samples and manufacturing portions can be found now, with lead instances of 10 weeks. Pricing for U.S. supply begins at $0.90 every in portions of 1,000. Click on right here for the datasheet.
The publish PTC thermistors save area appeared first on EDN.
