PolySwitch Resettable Devices
Automotive Devices
We have provided PPTC resettable devices for the
automotive industry for over 25 years. With the advent of
TS16949 and our continued involvement in the
automotive industry, we developed automotive specific
versions of our PolySwitch PPTC devices (AHS, ASMD,
AHRF, AHEF, AGRF and BD). These products are
qualified and sold under PS400 specification which is
derived from AEC-Q200, the standard for electronic
components used in the automotive industry. The key
difference between these product families and other
protection devices in our circuit protection product
portfolio is the qualification process followed according
to a series of rigorous tests related to the automotive
environment. As a result, they are characterized by
specific additional values determined post automotive
related testing.
