100R NTC Thermistor 5mm

NTC thermistors are resistors that exhibit a decrease in resistance as the temperature rises. This unique characteristic makes them an excellent choice for applications that require temperature sensing or control.

Composition and Functioning

 NTC thermistors are typically composed of a ceramic material infused with one or more metal oxides. The resistance reduction with rising temperature is due to the increased activity of free carriers (usually electrons) within the semiconductor material.

Applications and Advantages

 NTC thermistors find their use in a plethora of applications such as temperature control, temperature measurement, current limiting, and power sensing due to their unique behavior. A key benefit of NTC thermistors is their often non-linear resistance-temperature relationship, enabling them to deliver more precise measurements within a certain temperature range.

Common Use Cases 

• Motor temperature measurement in the automotive industry
• Temperature control in household appliances
• Thermal safety devices
• Various industrial process control applications

Note

It is crucial to remember that NTC thermistors usually function with a certain degree of accuracy within a specific temperature range. Therefore, choosing the right NTC for a specific application is of utmost importance.
