2. What is the maximum circuit voltage (V max )
3. What is the maximum fault current (I max )
4. What is the preferred form factor
Note: Other factors including thermal derating and time to
trip characteristics may be important application
considerations. Please refer to the full Bourns® data sheet of

Bourns® PPTCs are certified under UL, CSA, IEC and
TÜV registration programs.
The maximum current a PPTC device can pass without
interruption.
The maximum fault current a PPTC device can
withstand without damage at the rated voltage.
The minimum current that will switch a PPTC from the
low resistance to the high resistance state.
The peak current that flows through a PPTC or wire
during a short circuit or arc back.
A characteristic of the PPTC device that describes the
large increase in resistance as the device reaches its
switching (trip) temperature.
The maximum resistance one hour after a PPTC device
has been tripped and power has been removed.
The maximum resistance one hour after a PPTC surface
mount device has been reflow soldered.
The maximum voltage a PPTC device can withstand
without damage at the rated current.
