Tyco Electronics, a pioneer of polymeric positive
temperature coefficient resettable devices, has developed
several material platforms to help protect battery
applications. Each of these material platforms offers
different performance characteristics, allowing the
engineer greater design flexibility. PolySwitch devices
for battery protection include SRP, LTP, LR4, VTP, VLP,
VLR and MXP series, disc, and special application strap
devices.
