    Electrical Performance of MZ126A PTC Thermistor


    No.ItemRequirementsTest condition and method
    5.1Nominal resistance value12Ω±30%3Under the condition of 25℃, the DC resistance value of the thermistor measured with sufficiently low power consumption.
    5.2Working current
    (No action current)
    25℃ /170mA
    60℃ /130mA
    No action for 60 minutes
    Connect an ammeter in series with the test loop, then keep the product at a specified temperature (25°C), apply a specified current (140mA) and voltage (220V), and observe the current change displayed by the ammeter within a specified time.
    5.3Operating current
    (Protection current)

    ΔR/Rn≤20%
    The power supply voltage is 220VAC, the current is 2.0A, and the power is turned on for one minute and the power is cut off for ten minutes. The resistance change rate does not exceed the requirements.
    5.5Withstand voltage≥270V
    ΔR/Rn≤20%
    Apply the specified maximum voltage to the sample, and the resistance change rate does not exceed the specified value.


    Working Principle of MZ126A PTC Thermistor


    Connect the PTC thermistor in series in the load circuit. When the circuit is in normal working condition, the current through the PTC thermistor is less than the rated current. The PTC thermistor is in the normal state and the resistance is small, which will not affect the normality of the protected circuit. jobs. When the circuit fails, the current greatly exceeds the rated current (2 times of the normal working current), and the PTC thermistor suddenly heats up, showing a high resistance state, so that the circuit is in a relatively "off" state for protection purposes. When the fault is removed, the PTC thermistor automatically returns to a low impedance state and the circuit resumes normal operation.
