5K NTC Thermistor 3mm

NTC thermistors are a type of resistor whose resistance decreases as temperature increases. This property makes them ideal for temperature sensing or control applications.

NTC thermistors are typically made of a ceramic material containing one or more metal oxides. As temperature increases, the activity of free carriers (usually electrons) within the semiconductor material increases, leading to a decrease in resistance. Due to this behavior, NTC thermistors are used in a wide range of applications including temperature control, temperature measurement, current limiting, and power sensing.

One of the main advantages of NTC thermistors is their often non-linear resistance-temperature characteristic. This allows them to provide more accurate measurements within a specific temperature range. However, it's important to note that NTC thermistors typically operate with a certain accuracy within a specific temperature range, so selecting the right NTC for a particular application is crucial.

Common applications of NTC thermistors include motor temperature measurement in the automotive industry, temperature control in household appliances, thermal safety devices, and many industrial process control applications.
