V Working Principle Of The MZ21 PTC Thermistor 15P 100 OHM 25% 120C
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.
VI Application Of The MZ21 PTC Thermistor 15P 100 OHM 25% 120C
Inverter welding machine is more and more popular in the world since technoloy required for manufacturing,
