Application
◆ Over current protection in:
-Industrial electronics
-Consumer electronics
-Electronic data processing
◆ Short current protection
Features
◆ Short response time for rapid protection
◆ Automatic resetting once overcurrent is removed
◆ Leaded parts withstand mechanical stresses and vibration
◆ High thermal stability
When PTC is used as over-current protection element, the specification of the maximum non-action current and the maximum working voltage should be selected, at the same time, we should also consider the element size, rated zero-power resistance, the use of temperature range and other factors. Usually, the maximum current of PTC is 1.2-1.5 times of the maximum current when the circuit is working normally The voltage that may be applied to the PTC under normal or abnormal conditions should not be greater than its maximum operating voltage.
