Fuses

A fuse is an electric component connected in series with a circuit and designed to open up the circuit if an overload current flows through it, protecting electric components in the circuit from possible damage. Fuses come in many varieties, and among them is the F0805B0R50FWTR fuse series.

F0805B0R50FWTR Application Field

The F0805B0R50FWTR series are SMT chip fuses for surface mount applications, developed and manufactured by a number of Japanese manufacturers. They are small and light, and feature excellent solderability and superior insulation properties. These features make them ideal for use in high frequency switching mode power supplies, power amplifiers, and current sensing circuit applications in various small, electronic products.

F0805B0R50FWTR Working Principle

The F0805B0R50FWTR fuses operate on the principle of overload current-controlled electronic components. When an overload current occurs, the fuse will open the circuit in order to protect the attached electronic components. The fuse is made up of a metal strip that, when an overload current flows through it, causes the metal strip to melt, opening the circuit.

The F0805B0R50FWTR series of SMT chip fuses have very tight current sensitivity and are designed to operate within the range of 0.5A to 1.25A. The fuse has an extremely small form factor that enables it to be installed in tight and compact locations, making it ideal for use in surface mount boards with limited space. Additionally, the fuse is designed with an extremely high current surge capability that ensures it is able to protect attached components, even in the case of an intense overload current.

Conclusion

The F0805B0R50FWTR series of SMT chip fuses are ideally suited for a wide range of applications, due to their small form factor, excellent solderability, superior insulation
