PolySwitch® low resistivity SMD (surface-mount device) is
a versatile device well suited for general applications which
have space-constrained, low power dissipation and high
environmental reliability requirements.
The devices can help provide both overcurrent and
overtemperature protection for battery pack PCMs
(protection circuit modules), circuit PCBA and signal/power
I/O interface. The resettable feature ensures the device will
“Trip” and protect the application during the faults and yet
regain the functions once the error is removed.
