Silicone Coated MZ126A 25C PTC Thermistor 10MM Positive Temperature Coefficient Resistor

Silicone Coated PTC Thermistor MZ126A 12 OHM 30% 270V 2A For Electric Welding Machine

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.

Hello! MZ6 is a commonly used positive temperature coefficient thermistor in the industry. The head size of the product is 6MM, and the specific parameters of the product cannot be seen. This type of product mainly includes switching temperature, resistance, and overcurrent Protection is still used on energy-saving lamps. We are specialized in producing such products, and hope to help you.

5.2	Working 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.
5.3	Operating current (Protection current)	25℃ 340mA ＜300 seconds action	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.
5.4	Withstand current capability (Maximum current)	2.0A 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.
5.5	Withstand voltage	≥270V ΔR/Rn≤20%	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.
