Cautionary Notes
1.
Operation beyond the specified maximum ratings or
improper use may result in damage and possible
ele
ctrical arcing and/or flame.
2.
These Polymer PTC (PPTC) devices are intended for
protection against occasional overcurrent/
overtemperature faul
t 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. U
se in AC voltage applications
should be first discusse
d 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 failu
re.
