MQ 125TR

MQ125TR Application Field and Working Principle

The MQ125TR is a type of fuse that is used in a wide range of electronic devices for a variety of purposes. It is typically used to protect electrical components from power surges or other sudden increases in current. The MQ125TR fuse is a low cost, temperature-resistant component designed to offer reliable circuit protection. It has an operating temperature range of -55℃ to +125℃ and is intended for use in electrical systems rated up to 32V DC or 24V AC.

The MQ125TR fuse has a cylindrical shape and a high-temperature plastic tube. The internal components of the fuse include two pieces of metallized polyester film, a ceramic body, two electrodes, and a lead wire. The electrodes are connected to the ends of the metallized polyester film that is coated on both sides with a solid-state conductive material. When exposed to an over-current condition, the metallized polyester film melts, creating an open circuit and effectively cutting off the current. This protects the associated electrical components from damage due to overload.

The MQ125TR is used to protect a variety of circuits, such as computer power supplies, industrial manufacturing machinery, audio/video equipment, automotive electronic systems, and other consumer electronics. It is also used as a safety device in the event of a catastrophic failure, such as a power surge or short circuit. The fuse can be used as a component in a circuit protection network or as an individual component.

The MQ125TR has been designed with a unique construction that ensures high reliability and performance. It is RoHS compliant and UL certified, which makes the fuse suitable for use in a wide variety of applications. The fuse can be used with a variety of terminal blocks, including the SPST, DPDT, and SMD types. It also provides a high level of overvoltage protection and a low resistance that enables it to respond quickly to current changes.

The MQ125TR fuse is an ideal solution for protecting against a wide range of electrical hazards, from over-voltage to surge protection. With its robust construction and reliable performance, the MQ125TR is one of the most reliable types of fuses available on the market today.
