* Due to “lead free/RoHS6” construction of these PTC
devices, the required Temperature and Dwell Time
in the “Soldering” zone of the reflow profile are
greater than those used for non-RoHS devices.

1. Operation beyond the specified maximum ratings or
improper use may result in damage and possible
electrical arcing and/or flame.
2. These Polymer PTC (PPTC) devices are intended for
protection against occasional overcurrent/
overtemperature fault conditions and may not be
suitable for use in applications where repeated and/
or prolonged fault conditions are anticipated.
3. Avoid contact of PTC device with chemical solvent.
Prolonged contact may adversely impact the PTC
performance.
4. These PTC devices may not be suitable for use in
circuits with a large inductance, as the PTC trip can
generate circuit voltage spikes above the PTC
rated voltage.
