【1】Ceramic PTC Themistors For Circuit Protection
Outline
■The 16V series PTC for circuit Protection is best as the sensor of electric detector, the protection of motor for car and the protection of low voltage circle because of low resistance value. It is possible to use many times if it was got rid of abnormality causes such as over current, and the resistance value will be restored.
Distinction
The response speed to the over current is fast because of small size.
It keeps protecting the circuit for abnormality until turning off power.
It will return to former low resistance quickly and can be used repeatedly if the power supply is turned off.
The noise is not generated because it doesn't have mechanical contact.
