Thermistor Negative Temperature Coefficient (NTC) 22D-11, 11MM Diameter, 22Ω Zero Power Resistance @ 25℃, 5A Maximum Steady State Current.
NTC (Negative temperature coefficient) thermistor is a semiconductor made from metallic oxides. It exhibits an electrical resistance that has a very predictable change with temperature. The resistance varies significantly with temperature, more so than in standard resistors. They are extremely sensitive to temperature change, very accurate
and interchangeable. They have a wide temperature envelope and can be hermetically sealed for use in humid environments. This Thermistor type is used mainly in SMPS power supply circuit protection to limit inrush currents or surge when the system is initially powered On.
