Thermistors – NTC Temperature Sensors

Explore thermistors and NTC temperature sensors for electronic circuits, temperature measurement, monitoring and protection applications. A thermistor changes its electrical resistance according to temperature, allowing electronic circuits to detect and respond to thermal variations.

Choose the appropriate NTC thermistor according to nominal resistance, operating temperature range, tolerance, B value, dimensions and electrical characteristics. Thermistors are commonly used in power supplies, battery systems, temperature controllers, household appliances and electronic protection circuits.

How to Choose an NTC Thermistor

When selecting an NTC thermistor, check its nominal resistance, usually specified at 25°C, as well as the B value, tolerance, operating temperature range and physical dimensions. These parameters determine the resistance-temperature characteristic of the component.

NTC thermistors are commonly used for temperature sensing, thermal monitoring, inrush current management and protection circuits. For replacement applications, verify the resistance value and thermal characteristics of the original component before selecting an alternative.
