Fixed Inductors Introduction

A fixed inductor, or inductor for short, is a two-terminal electronic component possessing predetermined electrical characteristics. An inductor is often used to store and or vary electrical energy, usually in an AC or DC circuit. When used in a DC circuit, an inductor or a coil serves as a passive component which creates a voltage across its terminals at a certain frequency, which is then delivered to a load dependent upon the characteristics of the inductor or coil. Inductors can also be used as filtering components, by transforming high-frequency AC signals into lower frequency components and by absorbing excessive signal energy from a DC power source.

9130-32 Application Field and Working Principle

The 9130-32 is a rare-earth iron-powder soft-magnetized fixed inductor with a rated inductance of 30uH. It features a core material that is a combination of rare-earth and iron-powder material which provides a high permeability and low coercive force. The 9130-32 is widely used in wireless communication systems such as base station applications and wireless local area networks (WLANs).In terms of its working principle, when current passes through the inductor, it induces a magnetic field. The total inductance of the inductor is determined by its geometry and core material. The 9130-32 is designed to provide high permeability and low coercive force. The combination of the two allows for the inductor to store energy in the form of the magnetic field. When voltage is applied across the inductor, the magnetic field is weakened, releasing the energy. The 9130-32 also features a wide range of inductance values, from 30uH to 150uH, with multiple winding configurations.The 9130-32 also has high power and low profile features, making it ideal for high density circuits. Its winding structure allows for a higher current rating and less space requirement. In addition, the 9130-32 is designed to be robust against vibration, capable of operating temperatures up to 125 degrees C with long life-time operation.

Conclusion

The 9130-32 fixed inductor is ideally suited for high density circuits, as it has a low profile and high power capabilities. The combination of rare-earth and iron-powder cores allows for a wide range of inductance values to be achieved, making it ideal for a variety of applications ranging from base station applications and WLANs to high power industrial equipment. The 9130-32 is also designed for robust operation in high-vibration applications with a long operational life and high temperature capability.
