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. P
rolonged 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 a
ir flow could
affect electrical performance and/or result in
device failure. Consult Bel Fuse engineering.
