Fixed Inductors

Fixed inductors, sometimes known as inductors, coils, chokes, or reactances, are passive electronic components used in the electrical engineering field. Their purpose is to provide a controlled inductance to the circuit. They come in various forms and can handle varying levels of voltage and current.

The CB2518T4R7MRV is a fixed inductor used in electronic equipment. It is a two-winding centennial choke with a rated inductance of 2.8 mH and a DC resistance of 23.7 ohms. It has a 50V maximum DC voltage and a 0.5 A maximum DC current. It comes standard with a RoHS-compliant tin-lead finish and has a storage temperature range of -40oC to +125oC.

Application Field

The CB2518T4R7MRV is used in a variety of electronic circuits including telecommunications, instrumentation, and audio/video equipment. It is suitable for power electronics, signal filters, and digital signal processing. It also has applications in DC-DC converters, voltage stabilizers, and waveform converters.

Working Principle

The working principle of the CB2518T4R7MRV is nonlinear. It consists of two coils of wire that can be either connected together or wound independently. When current passes through one coil, it induces a magnetic field that attracts the other coil due to the attractive force of magnetic flux. As a result, the second coil also experiences a current. This creates a nonlinear relationship between the current and voltage of the inductor. This is known as magnetic coupling and it allows for the increased efficiency of electricity.

The two coils in the CB2518T4R7MRV are designed for use in transmission applications, where two independent sources are connected together and require a form of buffering between them. This allows for the conversion of a signal from one form to another at each end of the transfer, reducing the amount of interference that can occur between them.

The CB2518T4R7MRV also has noise suppression capabilities. It is designed to provide a high degree of attenuation for signals in both the low-frequency and high-frequency ranges. This helps reduce the amount of noise that can be present in the circuit and prevents interference between different components in the system.

Conclusion

The CB2518T4R7MRV is a fixed inductor used in a variety of electronic circuits, including telecommunications, instrumentation, power electronics, and digital signal processing. Its working principle is based on the nonlinear relationship between the current and voltage induced by the two coils of wire. It has a high degree of attenuation for signals in both the low-frequency and high-frequency ranges, providing excellent noise suppression capabilities.
