The company not only meets the increasing demand in Southeast Asia, but also expands Murata Group's global market expansion and continuous technological innovation; In addition, the company continuously improves its production to meet the demand for high functionality of electronic devices and the popularization and extension of new applications. Murata Electronics' continuous development has become one of the leading companies in electronic components.
PTC Resettable Fuses are composed of polymer materials and conductive particles, etc., after special processing, conductive particles form a chain conductive path in the polymer material. In normal working condition, the fuse is in a low resistance state, allowing the current to pass smoothly. However, once an abnormal overcurrent occurs in the circuit, the heat generated by the large current will cause the polymer material to expand rapidly, cut off the conductive path composed of conductive particles, and make the fuse present a high resistance state, thereby preventing the current from continuing to flow. This change is reversible, when the power supply is cut off or the overcurrent disappears, the PTC resetable fuse can automatically restore to the low resistance state, without replacement, so it is widely used in the need for frequent protection and do not want to have a permanent break.

Murata Electronics - PTC Resettable Fuses: PTC Resettable Fuses are unique in that they are resettable. Unlike traditional disposable fuses, PTC fuses can be automatically restored to a low-resistance state after the fault is eliminated and the current returns to normal, without replacement, which greatly saves maintenance costs and time. This feature makes PTC resetable fuses widely used in situations where frequent protection is required and permanent disconnections are not desired. In terms of application fields, PTC resettable fuses widely cover many fields such as consumer electronics, medical equipment, computers and peripherals. For example, in portable devices such as smartphones and tablets, PTC fuses are used to protect batteries and charging circuits; In medical devices, they are used to protect sophisticated electronic components from electrical shocks. In computer systems, PTC fuses protect critical components such as hard drives and USB interfaces from overcurrent damage.
