    Surface Mount Package Chip NTC Thermistor 0402 0603 0805 SMD For Smartphone Tablet Automotive xEV Wearables Medical


    Description


    Chip NTC thermistors are thermally sensitive semiconductive resistors that are designed for temperature measurement and compensation. The portfolio covers NTC thermistors with excellent long-term stability in high-temperature and high humidity environment, e.g. for smart phone, tablet by small case size, automotive applications, LED modules and industrial applications. Tight tolerances of resistance and B value allow highly accurate temperature sensing capabilities.

    Temperature characteristics



    Examples



    To customers who use NTC Thermistors for the first time


    STEP 1:Please specify the required conditions.

    ①A basic constitution of circuit
    ②Reference voltage
    ③A range of temperature control and a range of an output voltage
    ④A target temperature and a target output voltage


    STEP 2:We’ll make a table and graphs of the main characteristics value

    ①An output voltage(the upper and the lower limit)
    ②Sensitivity(mV/℃)
    ③Accuracy in temperature
    ④Current of circuit


    STEP 3:We’ll change the circuit constant and simulate

    ①Decide the part number
    (1)B value and its tolerance
    (2)Resistance value R25 and its tolerance
    ②Simulate the resistance value of the peripheries of a fixed resistor and its tolerance


    We propose you the best circuit constant.


    Summary


    NTC Thermistor (chip type) is a temperature sensor that changes its resistance value as the surrounding temperature changes and it is applied to electronic devices for temperature detection and temperature compensation.
    NTC Thermistors are available in various sizes (01005~0603). Also, it has a wide range of resistance value and B-value.
    NTC Thermistors have narrow tolerance (±1%) and high accuracy from the very first, and the resistance value does not change much in high temperature and humid condition.It maintains high accuracy in both “initial state + actual usage environment”.
    ・It can contribute to highly-accurate temperature control in electronic devices.
    We carry out total support to our customers with design simulation and/or by supplying data on our official website.
