PTC thermistor

Passive components · Self-regulating

Switching PTC · 25 Ω cold · switches at 80 °C · resistance climbs steeply above it (motor start, degauss, heaters, over-current)

Try it on the benchThe lab drops it on an empty bench and opens its datasheet card.

Ratings and limits

How to use it

Self-regulating: as it heats past its switch temperature, resistance climbs a thousandfold and the current drops. Used in motor-start circuits, degaussing and self-limiting heaters.
