SC43B-2R7 Fixed Inductors: Application Field and Working Principle

The SC43B-2R7 fixed inductor is an electronic component manufactured by Sumida and is a type of inductor for radio frequency (RF) applications. It is one of the most widely used RF inductors, and is found in a variety of wireless communication systems, computer circuits, and audio circuits. In this article, we will discuss the application field and working principle of the SC43B-2R7.

Application Field:

The SC43B-2R7 is designed for use in a wide range of applications. it can be used in radio receivers and transmitters, computer circuits, audio circuits, and more. It is particularly well-suited for use in HF, VHF, and UHF radio communication systems, including Amateur Radio systems, two-way radios, and consumer electronics. It can also be used in mobile devices, such as cellular phones, as well as in wireless LANs.

Working Principle:

An inductor is an electromagnetic device that stores energy in a magnetic field. The SC43B-2R7 is a type of fixed inductor, which means that it is pre-made and cannot be adjusted or re-used. When an alternating current (AC) is applied to the SC43B-2R7, it creates a magnetic field around the inductor’s core, which stores energy. The inductance of an inductor is determined by its size and construction. The SC43B-2R7 has a high inductance and is therefore ideal for use in high frequency radio systems.When fully saturated, the SC43B-2R7 is able to handle up to 400 mA of AC current with minimal distortion. It is also able to withstand temperatures of up to 105°C (221°F).

Conclusion

The SC43B-2R7 is a versatile fixed inductor manufactured by Sumida. It is suitable for use in a wide range of applications, including radio receivers and transmitters, computer circuits, audio circuits, and more. Its high inductance and low distortion make it ideal for use in high frequency applications, such as Amateur Radio systems.
