How to Choose and Work with NTC Thermistors

NTC & PTC Thermistors

  • MF72


    Digikey Link

    Power NTC Thermistor

    The MF72 series Power NTC Thermistors provide inrush current suppression for sensitive electronics. Connecting a MF72 in series with the power source will limit the current surges typically created at turn on. Once the circuit is energized the resistance of the MF72 will decrease rapidly to a very low value, power consumption can be ignored and there will be no effect on normal operating current. Using the MF72 Power NTC Thermistor is a most cost-effective way to curb surge current and protect sensitive electronics from damage.


    Can be installed into the power circuits of:
    • Power supplies and inverters
    • Uninterruptible Power Supplies
    • Energy saving lamps
    • Electronic Ballasts
    • Filament Protection of various types of lamps
    • Some types of heaters

  • PTC Thermistors

    PTC Thermistors

    Digikey Link

    PTC thermistors act as thermal protectors for electrical motors. They are available with or without an insulated sleeve and have flexible connecting leads. PTC thermistors have a non-linear resistance/temperature response. At a specified temperature the resistance changes rapidly to a very high value.

    • Rapid response protection for electrical machines 

    • Compact size for easy assembly into windings 

    • Silvered copper leads

    Thermal Sensor MOXIE®

    Moxies are a family of, variable resistance thermal sensors having a highly specific "transition region." Within this transition region the devices typically exhibit a negative temperature coefficient ranging from 40% per °C to 200% per °C. Below the transition region they exhibit a linear "thermistor" characteristic of -2 to -4%/°C.


    Sensors for temperature protection, control and limiting. Voltage, current and frequency limiters in electronics.
    Examples: Overtemperature protector for power semi-conductors, such as transistors, power output stages, amplifiers.

  • MF51E


    Digikey Link



    High Precision NTC Thermistors for Extremely Accurate Temperature Measurement
    The MF51E NTC Thermistors were specially designed for use in electronic thermometers which require better than average accuracy. The extremely small size allows the thermistor to respond very quickly to tiny changes in temperature. The MF51E can be supplied un-calibrated with standard tolerances or calibrated and grouped according to R at 37°C±0.01% for extreme interchangeability so as to eliminate the need for other calibrations.
