PolySwitch Resettable Devices
Automotive Devices
Raychem Circuit Protection has provided PPTC resettable
devices in the automotive industry for over 25 years. Until
recently, the products sold by Raychem Circuit Protection to
this industry were either custom products (TD and Chip series
devices) or our standard commercial versions of PPTC resettable
devices. With the advent of TS16949 and our continued
involvement in the automotive industry, we decided to develop
automotive specific versions of our PPTC resettable devices.
The result of this development is the four device families (AHS,
ASMD, AHRF and AGRF) featured in this section, along with
constant additions to these portfolios. These products are
qualified and sold under our PS400 specification which is
derived from AEC-Q200, the standard for electronic components
used in the automotive industry. The key difference between
these families and other protection devices in the Raychem
Circuit Protection portfolio is the qualification according to a
series of rigorous tests related to the automotive environment.
As a result, they are characterized by some specific additional
values determined post automotive related testing. Raychem
Circuit Protection is currently also working on offering single
use surface-mount fuses and varistor devices to the automotive
electronic market.
