PTC Thermistor Alloy Resistance Wire is for Temperature Sensitive Resistance
This alloy, which has middle grade resistance and high positive temperature coefficient of resistance, are extensively used in automatic temperature controlling, automatic power adjustment, regular current limiting, power saving, and service life improvement.
Resistance temperature coefficient: 0-100 ºC ≥ (3000-5000) X10-6/ºC Resistivity: 0-100ºC 0.13-0.60μΩ.m
We can supply the thermistor wire grade such as NiFe28, NiFe30.
The main grade is as following list:
| Chemical composition(%) | Resistivity (μΩ.m) | TCR (ppm/k) | |
| Nickel | Iron | ||
| 85~95 | Bal | 0.13 | |
| 75~85 | Bal | 0.15 | |
| 70~75 | Bal | 0.2 | +3980 |
| 60~65 | Bal | 0.25 | +3933 |
| 50~55 | Bal | 0.32 | +3832 |
| 50~55 | Bal | 0.36 | +3139 |
| 50~55 | Bal | 0.4 | |
| 45~50 | Bal | 0.5 | +3100 |
| 45~50 | Bal | 0.6 | |
