The TRF011Z with PTC Resettable Fuses Through Hole,P=5.1mm,L=10mm RoHS is a thermal fuse or resettable fuse manufactured by Taiwanese electronic components company TLC. It is a type of circuit protection instrument, more specifically, a polyfuse. It is a type of PTC thermistor with a bimetallic disc, when the temperature reaches a specific threshold, it can activate and create a short circuit (open circuit). This effectively protects the electronic components in the circuit from any damage,such as overvoltage or short circuits. The TRF011Z is a P=5.1mm, L=10mm RoHS resettable fuse, it has a recovery temperature of 75 °C and a rated operating current of 10 amperes. It is an RoHS compliant product. This product is ideal for use in areas where circuit protection is of great importance, such as computers, consumer electronics, and automotive applications.
