VISHAY AMETHERM SL22 Series 7 Ohm NTC Thermistor

The VISHAY AMETHERM SL22 Series 7 Ohm NTC Thermistor (SL22 7R010) is a high-performance, radial-leaded component designed to protect sensitive electronic circuits from damaging inrush currents. By presenting a high initial resistance that quickly decreases as it heats up, this device effectively limits the surge of current when equipment is first powered on, such as in switching power supplies and other power devices.

Constructed as a robust disc type with a 22mm diameter, this thermistor features a resistance of 7 ohms at 25°C and is rated for circuits of up to 480VAC. Its rapid thermal response, characterised by a 94-second thermal time constant and a dissipation constant of 32.4mW/°C, ensures reliable and swift protection for connected components. This helps prevent premature failure and extends the operational lifespan of your equipment.
