Product Description

China NiFe ferro nickel P-4500 PTC alloy wire for thermistor resistance

We can produce many kinds of PTC resistance wire.
If you have special requirements on the temperature coefficient of resistance and diameter, please feel free to let us know.
While you order 0.15mm dia, if you want the resistivity 0.23 and the PPM is 4650, you can write NF23-0.15-4650. Then we will know what exact you like and will quote you accordingly.
