Part Numbering System for Radial-leaded Devices
WARNING:
Operation beyond the maximum ratings or improper use may result in device damage and possible electrical arcing and flame.
The devices are intended for protection against occasional overcurrent or overtemperature fault conditions and should not be
used when repeated fault conditions or prolonged trip events are anticipated.
Contamination of the PPTC material with certain silicon based oils or some aggressive solvents can adversely impact the
performance of the devices.
Device performance can be impacted negatively if devices are handled in a manner inconsistent with recommended electronic,
thermal, and mechanical procedures for electronic components.
Operation in circuit with a large inductance can generate a circuit voltage (L di/dt) above the rated voltage of the
PolySwitch resettable device.
