Cautionary Notes
1. Operati
on 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 fa
ult 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 intende
d 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.
