I Description Of The PTC Thermistor MZ126A 12 OHM 30% 270V 2A
PTC126A is the thermistor model PTC: Positive Temperature Coefficient 126A: 12 Ohm 6A
Thermistors are divided into positive temperature coefficient thermistors (PTC) and negative temperature coefficient thermistors (NTC). At present, PTC mainly includes polymer material PTC and ceramic PTC, and ceramic PTC has a higher overvoltage tolerance. The PTC of molecular materials is good, but the response speed of PTC of polymer materials is faster than that of ceramic PTC. Generally, ceramic PTC cannot achieve low resistance, and low resistance PTC uses polymer materials.

|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.|
|Connect an ammeter in series with the test circuit, then keep the product at a specified temperature (25°C), apply a specified current (340mA) and voltage (220V), and observe the current change displayed by the ammeter within a specified time.|
Withstand current capability
|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.|
|Apply the specified maximum voltage to the sample, and the resistance change rate does not exceed the specified value.|
V Working Principle Of The PTC Thermistor MZ126A 12 OHM 30% 270V 2A
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.
