Definitions
Agency Approvals
Bourns? PPTCs are certified under UL, CSA, IEC and
TüV registration programs.
Current, Hold (Ihold)
The maximum current a PPTC device can pass without
interruption.
Current, Maximum (Imax)
The maximum fault current a PPTC device can
withstand without damage at the rated voltage.
Current, Trip (Itrip)
The minimum current that will switch a PPTC from the
low resistance to the high resistance state.
Fault Current
The peak current that flows through a PPTC or wire
during a short circuit or arc back.
Positive Temperature Coefficient (PTC)
A characteristic of the PPTC device that describes the
large increase in resistance as the device reaches its
switching (trip) temperature.
Resistance, Post Trip (R1max)
The maximum resistance one hour after a PPTC device
has been tripped and power has been removed.
Resistance, Post Reflow (R1max)
The maximum resistance one hour after a PPTC surface
mount device has been reflow soldered.
Voltage, Maximum (Vmax)
The maximum voltage a PPTC device can withstand
without damage at the rated current.
Product Selection Worksheet
1. What is the normal circuit operating current (I hold)
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
each product at www.bourns.com/multifuse.
