Fixed Inductors

Fixed inductors are resistive components used to filter signals or store energy. They employ an electro-magnetic field generated by an electrical current through a coil to generate a magnetic field. This magnetic field can then be used to either store or filter a signal. The SD14-4R5-R is a type of fixed inductor, and it has a number of applications and working principles.

Applications

The SD14-4R5-R is a type of fixed inductor designed for use in electronic circuit design and power shape regulation. It has a wide range of applications in mobile phone systems, global navigation satellite systems, and power supplies for computers, medical equipment and other electronic devices. In these applications, the inductor can reduce electric noise and regulate power output.The SD14-4R5-R is also widely used in aerospace systems and electronic strain gauge systems. In aerospace systems, it can be used to reduce interference and regulate power. In electronic strain gauge systems, it can be used to measure pressure, acceleration, and strain.

Working Principle

When an electrical current passes through a coil of wire, it creates a magnetic field which stores potential energy. The SD14-4R5-R has an inner core of ferrite material which is surrounded by a coil made of high-quality metal wire. By passing an electrical current through the wire, it creates a flux which is then stored in the ferrite core. The stored electric energy is then used to filter or shape the signal. The SD14-4R5-R features a high coupling coefficient for high efficiency. Additionally, it also has an adjustable inductance range from 0.2 to 100uH, which can be used to fine-tune the output signal quality and power shape.

Conclusion

The SD14-4R5-R is a type of fixed inductor designed for use in electronic circuit designs and power regulation. It has a wide range of applications in mobile phone systems, global navigation satellite systems, power supplies, medical equipment, and aerospace systems. The inductor works by creating a magnetic field when an electrical current passes through a coil, which is then stored in a ferrite core for use in signal filtration and power regulation. Its adjustable inductance range, coupled with its high coupling coefficient, make it ideal for applications that require high efficiency and precision in signal quality.
