Working Principle
In parallel on the circuit, when the device does not operate, the resistance value is high (GΩ), low equivalent capacitance can be regarded as open circuit, almost no impact on the circuit. When there is an abnormal pulse, the internal resistance drops instantaneously after reaching the operating voltage value, and the current is released instantaneously. When the abnormal high voltage disappears, it returns to the high resistance state, and the circuit works normally.
Applications:
All kinds of power products,
isolators, inverters, medical equipment,
485 converter, communication products,
security products.
