Polymeric Positive Temperature Coefficient (PPTC) Resettable Fuses, commonly known as PTC Resettable Fuses, are an ideal replacement for traditional fast acting fuses. They take the place of traditional fuses by automatically resetting after over-current conditions. TRF250-120T-RF-B-0.5-2 is one such PTC Resettable Fuse. It is an ultra-low-current fuse designed for use in mobile devices, such as smart phones, tablets or wearables. This fuse offers superior protection against overload, surge and short circuit.

The TRF250-120T-RF-B-0.5-2 is an ultra-low-current, thermally protected Discrete Electronic Fuses. It features an integrated thermal protection sensor, allowing for virtually instantaneous response to a short-circuit condition, thus providing reliable over-current protection. The fuse is designed to automatically reset after current is reduced below the over-current threshold, thus eliminating the need for operator or maintenance intervention. This feature makes it particularly suitable for high-volume applications, and when guarding against electrical hazards.

The TRF250-120T-RF-B-0.5-2 can be used in a variety of applications, ranging from portable electronic devices to industrial machines, where circuit protection from short-circuit and over-current current conditions is necessary. It is designed to protect end equipment from catastrophic failure, by limiting the current supplied to the device. It is suitable for non-critical applications such as mobile phones and tablets, but also for critical applications such as medical implants and industrial equipment.

The TRF250-120T-RF-B-0.5-2 is based on a PTC resettable fuse element. Its working principle is based on the electrical characteristics of a particular polymer material, such as polyethylene, polypropylene or polystyrene. When an over-current condition occurs, current passes through the fuse element, causing it to heat up and expand, reducing its electrical resistance. This results in a reduction of current flow, limiting the injected current, and preventing damage to the end device.

The TRF250-120T-RF-B-0.5-2 is designed for high-volume, low-cost production. It provides significant over-current protection, with fast response time, low profile and low resistance. It is an ideal solution for applications that require high reliability and thermal protection in a small package. The fuse is suitable for any power supply circuit, providing essential protection against short circuit and over-current conditions.

In summary, the TRF250-120T-RF-B-0.5-2 is an ultra-low-current PTC Resettable Fuse designed for applications that require reliable over-current protection. It offers superior protection against overload, surge and short circuit. The fuse is based on a PTC resettable fuse element, responding to short circuit and over-current conditions by reducing current flow, preventing damage to end equipment. The TRF250-120T-RF-B-0.5-2 is suitable for any power supply circuit, providing essential protection against short circuit and over-current conditions.
