TR2/6125FF4-R

Fuses, often known as safety fuses, are an important electrical component in residential, commercial, and industrial settings. TR2/6125FF4-R is an axial-leaded, time-delay, surface mount fuse commonly used in power supply protection, high-voltage surge prevention, and other applications. In this article, we will discuss the application field and working principle of the TR2/6125FF4-R.

Application Field of TR2/6125FF4-R

The TR2/6125FF4-R has a variety of applications, including protecting power supplies from short circuits and overcurrent conditions. Furthermore, it is widely used in protecting sensitive electronics from high voltage surges and in line-conditioning applications that require low-voltage, high-current fuses.

The TR2/6125FF4-R is designed for use in DC circuits and is commonly found in power supplies, UPS systems, portable electronics, automotive, medical, and industrial applications. It can also be used in AC circuits when paired with an appropriate overcurrent protection device.

Working Principle of TR2/6125FF4-R

The TR2/6125FF4-R is an axial-leaded, time-delay, surface mount fuse. It is designed to open the circuit when current exceeds the rated limit. The TR2/6125FF4-R fuses are UL recognized with an I2T rating (current squared multiplied by time) of 20 A2.s. They have a time-delay feature that allows a small amount of overcurrent to pass before the fuse opens. This prevents nuisance tripping that can occur in short-circuit or overcurrent conditions.

The TR2/6125FF4-R has a response time of 0.25 seconds when operated at 500 VDC. The fuse has a current rating of 6.3A, with a minimum interrupting rating of 4000A at 500 VDC. In addition, it has a leakage current of less than 1mA, provides overvoltage protection of up to 600V, and operates at temperatures between -55°C and +125°C.

Conclusion

The TR2/6125FF4-R is an axial-leaded, time-delay, surface mount fuse. It is a versatile device that can be used in a variety of applications, such as power supply protection, high-voltage surge prevention, and line-conditioning. Its time-delay feature allows a small amount of overcurrent to pass through before the fuse opens, preventing nuisance tripping that can occur in short-circuit or overcurrent conditions. It has a current rating of 6.3A, and a minimum interrupting rating of 4000A. In addition, it has a leakage current of less than 1mA, and operates at temperatures between -55°C and +125°C.
