熱敏電阻自恢復保險絲3，其基本原理是一種能量的平衡，當電流流過元件時產生熱量，所產生的熱量一部分散發到環境中去，一部分增加了高分子材料的溫度。在工作電流下，產生的熱量和散發的熱量達到平衡電流可以正常通過，當過大電流通過時，元件產生大量的熱量不能即時的散發出去，導致高分子材料溫度上升，當溫度達到材料結晶融化溫度時，高分子材料集聚膨脹，阻斷由導電粒子組成的導電通路，導致電阻迅速上升，限制了大電流通過，從而起到過流保護作用。當轉接頭應用(如隨身碟等儲存裝置或手機)此熱敏電阻自恢復保險絲3器件後，電流超過設定值時，該熱敏電阻自恢復保險絲3將對電路進行斷開，從而起到保護轉接頭兩端設備的作用；同時，將轉接頭拔下後，由於熱敏電阻自恢復保險絲3的特性。Thermistor self-recovering fuse 3, the basic principle is a kind of energy balance, when the current flows through the component generates heat, part of the generated heat is emitted into the environment, and part of the temperature of the polymer material is increased. Under the working current, the generated heat and the dissipated heat can reach the equilibrium current, and when the excessive current passes, the large amount of heat generated by the component can not be immediately dissipated, causing the temperature of the polymer material to rise, when the temperature reaches the melting temperature of the material. When the polymer material aggregates and expands, blocking the conductive path composed of the conductive particles, causing the resistance to rise rapidly, restricting the passage of a large current, thereby providing an overcurrent protection. When the adapter is applied (such as a storage device such as a flash drive or a mobile phone), after the thermistor self-recovers the fuse 3 device, when the current exceeds the set value, the thermistor self-recovery fuse 3 will disconnect the circuit, thereby Protect the function of the equipment at both ends of the adapter; at the same time, after the adapter is unplugged, the characteristics of the fuse 3 are self-recovery due to the thermistor.
