FLSR2.25TXID Application Field and Working Principle

Introduction

FLSR2.25TXID is an electronic fuse used to protect devices and systems from electrical overloads. By combining the characteristics of the fuse\'s current limiting resistor and the thermal characteristics of its sensing element, FLSR2.25TXID offers improved protection over other types of fuses.The FLSR2.25TXID is a fast acting, self-resetting, thermal fuse that can be used in a wide range of applications. This fuses are designed specifically to protect circuits in which slow-blow fuses would be inadequate, such as in the circuit where a large amount of shielding, such as EMI/RFI shielding, or other resistance-degrading devices are present.

Application Field

The FLSR2.25TXID fuse is used for a variety of applications, ranging from consumer and commercial electronics to industrial and transportation systems. It is ideal for use in high current, fast acting, mission critical applications requiring long service life. In consumer electronics applications, the FLSR2.25TXID fuse is used in over current protection in cell phones, portable audio equipment, laptop computers, MP3 players and other digital devices. It also offers enhanced protection for the displays and graphics systems found in such devices.In commercial and industrial settings, the FLSR2.25TXID fuse is often used in machines, robotics, motors and power supplies, amongst many other applications. It is particularly well suited for use in high temperature environments, such as those found in restaurants and food processing plants, due to its high thermal temperature tolerance.In the transportation industry, FLSR2.25TXID fuses are often used in airports to provide protection for navigational instrumentation, emergency lighting and the primary power sources employed by such systems.

Working Principle

The FLSR2.25TXID uses a combination of a current limiting resistor and a thermal sensing element to provide protection for devices and systems. When the electrical load exceeds the fuse\'s rating, a fast rise in temperature is detected by the thermal sensing element, triggering the fuse to open. The current limiting resistor limits the current flow through the fuse, reducing the amplitude of the current spike that could otherwise develop, thus protecting the system being protected.The combination of the current limiting resistor and the thermal element offers improved protection from electrical overloads compared to other types of fuses, such as the slow-blow or fast-blow variety. The FLSR2.25TXID\'s fast response time and long service life make it ideal for high current, mission critical applications in numerous industries.

Conclusion

The FLSR2.25TXID is an electronic fuse designed to offer enhanced protection for electronics and devices from electrical overloads. It combines a current limiting resistor with a thermal element, allowing for an improved response time and a long service life. This fuse is used in a wide range of applications, ranging from consumer and commercial electronics to transportation and industrial systems. With its enhanced protection and fast response time, the FLSR2.25TXID can be used in mission critical applications requiring extended service life and robust protection.
