Note on Electrical Characteristics

Vocabulary

Ihold = Hold current: maximum current device will pass without tripping in 23ºC still air.

Itrip = Trip current: minimum current at which the device will trip in 23 ºC still air.

Vmax = Maximum voltage device can withstand without damage at rated current (I max)

Imax = Maximum fault current device can withstand without damage at rated voltage (Vmax)

Pd typ = Typical power dissipated from device when in the tripped state at 23 ºC still air.

Rmin = Minimum resistance of device in initial (un-soldered) state.

R1max = Maximum resistance of device at 23 ºC measured one hour after tripping or reflow soldering of 260 ºC for 20 sec. Value specified is determined by using the PWB with 0.150”*1.5oz copper traces.

Caution: Operation beyond the specified rating may result in damage and possible arcing and flame. Specifications are subject to change without notice. Po

Polymeric PTC Selecting Guide

a.Determine the following operating parameters for the circuits:

*Normal operating current (Ihold) *Maximum interrupt current (Imax)

*Maximum circuit voltage (Vmax) *Normal operating temperature surrounding device (minºC/maxºC)

b.Select the device form factor and dimension suitable for the application:

*Surface Mount Device (SMD) *Axial Leaded Device (ALD) *Other Customized Form Factors

*Radial Leaded Device (RLD) *DISC Device

c.Compare the maximum rating for Vmax and Imax of the PPTC device with the circuit in application and make sure the circuit’s requirement does not exceed the device rating.

d.Check that PPTC device’s trip time (time-to-trip) will protect the circuit.

e.Verify that the circuit operating temperature is within the PPTC device’s normal operating temperature range.

f.Verify the performance and suitability of the chosen PPTC device in the application.
