Description of the invention: [Technical field to which the invention pertains] The J invention relates to a passive component, particularly to an over-current & and over-temperature protection component. [Prior Art] _, the resistor is used to protect the circuit from overheating or flowing through! Damaged by current. A thermistor typically contains two electrodes and a f-position between the two electrodes. The f-resistance material has a low resistance value at room temperature, and when the temperature rises to a critical temperature or an overcurrent is generated on the circuit, the resistance value can immediately jump thousands of times or more, thereby suppressing excessive current flow. To achieve the purpose of circuit protection. After the Shida/m degree drops back to room temperature or there is no more overcurrent on the circuit, the thermistor can return to the low resistance state and the circuit can be re-operated normally. This reusable advantage makes the thermistor replace the fuse and is more widely used in high-density electronic circuits. Future electronic products will develop toward a light, thin, short, and small trend to make electronic products more miniaturized. The passive component occupies the largest area in the electronic product, so if the passive component can be effectively integrated, the electronic product can achieve light, thin, short and small functions. 201246238 The design of the known thermistor elements is based on a single function early-loop design.
