POLYSWITCH RESETTABLE DEVICES Automotive Devices We have provided PPTC r esettable devices for the automotive industry for over 25 years. With the advent of TS16949 and our continued involvement in the automotive industry, Littelfuse PolySwitch team developed automotive-specific versions of PPTC devices (femtoASMDC, picoASMDC, nanoASMDC, microASMD, miniASMDC, ASMDC, nanoASMDCH, AHS, ASMD, AHRF, AHEF and AGRF). These products are qualified and sold under the PS400 specification which is derived from AEC-Q200, the standard for electronic components used in the automotive industry. The key difference betw een these product families and other protection de vices in our circuit protection product portfolio is the qualification process that is followed that includes a series of rigor ous tests r elated to the automotive en vironment. As a result, they are characterized by specific additional values determined following automotive-related testing.
