NTC Thermistors are temperature-sensitive passive components made from semiconductor ceramic materials whose resistance decreases as temperature increases. They provide a predictable resistance-versus-temperature characteristic and are commonly supplied as discrete sensing elements.

Within the broader Passive Components category, NTC thermistors are primarily used for temperature-related functions where a resistive element changes value in response to thermal variation.

• Core principle: negative temperature coefficient behavior (resistance drops with rising temperature).
• General role: converts temperature changes into corresponding resistance changes.
• Category scope: includes NTC thermistor elements intended for temperature-dependent resistive control or measurement.
