Fixed inductors are components widely used in electrical and electronic systems. These are usually characterized by a combination of inductance, resistance, capacitance and other properties, all affecting their performance. RC-7-B is a type of fixed inductor offering excellent performance in a wide range of applications. In this article we look at the application field and working principle of RC-7-B.

Application Field

The RC-7-B is a broadband fixed inductor, ideal for use in systems such as radio-frequency circuits, digital signal processing and signal detection. It is well suited for high-frequency communication systems, providing excellent performance in the range of 0 to 3 GHz. Additionally, RC-7-B inductors are often used as the main component in electric motor control systems.

The RC-7-B has a remarkably high power rating, allowing it to operate at temperatures up to 70°C with a maximum dissipation of 1W. Furthermore, the device is highly efficient, with a power factor of more than 0.98, bringing down the total power consumption. The block turns-ratio of the RC-7-B is also impressive – typically ranging from 16:1 to 32:1.

Working Principle

The RC-7-B is based on a three-terminal arrangement, where the input voltage is applied across the inner two terminals and the inductance is present across all the terminals. The third terminal acts as an output, and the current flowing through it can vary depending on the input voltage. When a sinusoidal voltage is applied, the output current is sinusoidal and has an amplitude that is proportional to the input voltage.

The RC-7-B works on the principles of magnetic induction. As voltage is applied across the terminals, current flows through the wire, generating a magnetic field. This field interacts with the inductor’s magnetic circuit, creating an induced field. This field induces a current in the coil, which in turn creates an electromagnetic field opposing the flow of current and generating a magnetic force.

The RC-7-B also has a built-in damping effect, reducing the amount of reflected waveform at a good level. This damping function facilitates excellent immunity against electrical surge and overvoltage, offering good protection to the system components. Further, the high-frequency characteristics of the RC-7-B allow it to handle signals with a frequency range up to the 3-GHz range, ensuring unmatched performance for the system.

Conclusion

The RC-7-B fixed inductor from Recom is designed for signal processing tasks such as radio-frequency communications, digital signal processing and motor control. It is efficient and offers excellent performance over a wide frequency range, and comes with built-in damping to improve surge protection. All this makes RC-7-B one of the best options for fixed inductors.
