VLR170

VLR Series www.DataSheet4U.com PolySwitch Battery Protectors New VLR Low Resistance PolySwitch Resettable Strap Devices Enhance Thermal Protection for Li-Ion and NiMH Battery Packs Tyco Electronics Corporation has developed the next generation in its popular line of PolySwitch® PPTC (Polymeric Positive Temperature Coefficient) resettable strap devices. The VLR230 and VLR170 devices provide very low series resistance and enhanced thermal protection for Lithium-Ion (Li-Ion) and Nickel Metal Hydride (NiMH) rechargeable battery packs typically used in cell phones, laptops, radios, camcorders, and other portable equipment. VLR devices are well suited for single-cell Li-Ion applications. The VLR device's narrow, low-profile form factor allows it to be welded directly onto battery cells, thus saving space and added installation costs. VLR devices lower trip temperature (~5ºC lower compared to the VTP strap devices) and fast timeto-trip (typically 2.4 seconds or better at 10A) provide enhanced protection for rechargeable battery applications, while allowing longer battery pack life and extended equipment operation time. Target Applications: Mobile phone battery packs Cordless phone battery packs Mobile radio packs Computer battery packs Camcorder battery packs Features: Broadest range of resettable fuses available in the industry Current rating of 100A Voltage rating of 12V Agency recognition pending Industry fastest time-to-trip Industry lowest resistance devic...
