Cautionary Notes

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.

5. These devices are intended for use in DC voltage

applications only. Use in AC voltage applications

should be first discussed with Bel Fuse

engineering.

6. Not recommended for use on potted or conformal

coated PCB’s. Restriction of free air flow could

affect electrical performance and/or result in

device failure. Consult Bel Fuse engineering.
