Polymer PTC Resettable Fuse JK series, offer full components
Resettable fuse 250V 40MA 0.04A PPTC JK250 series JK250-040U
Working Principle
As an overcurrent protection component, traditional fuse only protect one time and need to replace another once burned. The recoverable fuse, one newly overcurrent protection component, has overcurrent protection and auto recoverable.
Overcurrent protection
JKPPTC component is at the low resistance state to ensure the circuit work normally. When encountered short circuit or high current, JKPPTC component can heat by itself to improve resistance with limiting small enough current to protect circuit.
Environment Temperature Effective
The current is on the decrease by recoverable fuse when environment temperature is higher than 25°C. The current can 100% recover by recoverable fuse when the operating temperature is 20°C in the circuit. If more than two time current occurs, the recoverable fuse can work.  The higher environment temperature and current passe through, the shorter the working time is.
Classification
1.Keeping Current(IH):  the highest current when don't touch PPTC recoverable fuse under 25 ºC quiescent environment
2.Touching CurrentL(IT): The lowest current when PPTC recoverable fuse resistance becomes lowest one to the highest one under 25ºC quiescent environment.
3.Max Voltage(V max): PPTC recoverable fuse can undertake max working voltage.
4.Max Current(I max):P 35 Â OTC recoverable fuse can undertake max currentÂ
5.Movement time(T trip):The max movement tine under the specified currentÂ
6.Movement Power(Pd typ):Dissipation power  when PPT recoverable fuse is in movement state under25ºC environment
7.Min Resistance (R min): the min zero power resistance under 25 ºC environment
8. Max Resistance: the max zero power resistance under 25 ºC environment

The military Wire Harness is an industry applied in the military, and the arms industry is a powerful industrial sector.
In China, the military industry mainly refers to the industrial departments and factories and other military units that mainly serve the national defense construction and directly provide weapons and equipment and other military supplies to the troops. Weapons products mainly include the weapons industry, aviation industry, shipbuilding industry, electronics industry, nuclear industry, aerospace industry, etc. The main products are guns, ammunition, tanks, military vehicles, military aircraft, military ships, military electronic equipment, rockets, missiles, military aerospace equipment, nuclear weapons and military clothing.
Typical requirements for military wire harnesses:
Excellent optical performance;
Strong connections to withstand shock and vibration;
Operating temperature range from -55°C to +125°C and beyond;
Lightweight design and compact size;
Combining high density and high channel count;
Low sensitivity to corrosion, pressure and humidity.
