PCB trace shunt resistor for low cost
solution.
The figure below shows outputcharacteristics of the
device when using a PCB resistive trace for a low
cost solution in replacement for a conventional
shunt resistor. The graph shows the linear rise in
voltage across the resistor due to the PTC of the
material and demonstrates how this rise in
resistance value over temperature compensates for
the NTC of the device.
The figure opposite shows a PCB layoutsuggestion.
The resistor section is 25mm x 0.25mm giving
approximately 150m
using 1ozcopper.Thedata for
the normalised graph was obtained using a 1A load
current and a 100
output resistor. An electronic
version of the PCB layout is available at
