Designed to limit unsafe currents while allowing constant safe current levels, resistance will "reset" automatically when the fault is removed and temperature polyfkse to a safe levels.
The trip current is the current at which the device is guaranteed to polyfsue. If too much current is passed through the device the device will begin to heat. Chassis Comfort and Convenience Emissions.
If you decline, your information won't be tracked when you visit this website. Polyfuses were developed to replace the earlier nickel-chromium ni-chrome fuses. The dimension of each product is included within each data sheets on the following pages.
Low capacitance polymer base product for protecting high speed data circuit from ESD damage and maintaining data integrity. Resettable Overcurrent Protection devices with various options: They were also used as to permit programming of Programmable Array Logic.

Resettable PTCs PolySwitch Devices - Littelfuse
If the overload current is to the left of the curve, the device will not operate. The sale and use of Littelfuse products is subject to Littelfuse Terms and Conditions of Sale, unless polyfuwe agreed by Littelfuse. PTCs hold and trip rating must be rerated when applied at conditions polyfise than room ambient. The device may not return to its original resistance value; it will most likely stabilize at a significantly higher resistance up to 4 times initial value.
To determine the opening time for the chosen device, locate the overload current on the X-axis of the appropriate T-C Curve and follow its line up to its intersection with the curve.
