NTC 8D-20 Circuit Protection Thermistors Inrush Current Limiter Resistance: 8 Ohms Max Steady State Current: 6.0 A Size: 20mm diameter, 5.5mm width, 10mm lead spacing Package of 2 pieces The 8D-20 Power NTC Thermistors provide inrush current suppression for sensitive electronics. Connecting a 8D-20 in series with the power source will limit the current surges typically created at turn on. Once the circuit is energized the resistance of the 8D-20 will decrease rapidly to a very low value, power consumption can be ignored and there will be no effect on normal operating current. Using the 8D-20 Power NTC Thermistor is a most cost-effective way to curb surge current and protect sensitive electronics from damage.
