Working Principle

Fixed inductors take advantage of Faraday’s Law, which states that a changing magnetic field produces an electric field, and vice versa. In the case of an inductor, an alternating current is applied to the coil. The changing electric field creates a magnetic field which produces an EMF in the coil in the opposite direction of the current. This EMF, known as the Back EMF, opposes the applied voltage, resulting in a net voltage drop along the component. The combination of the Back EMF and the voltage drop produce an inductive reactance, which is a measure of the opposition to AC current. The larger the inductance of the component, the greater the inductive reactance.

The AIUR-11-150K is designed to have a relatively low DC resistance, which reduces power losses due to the DC resistance of the component. In addition, it has excellent temperature characteristics, which ensures that the inductance remains steady over a wide temperature range. This is important for applications that require accurate performance in varying environments.

Conclusion

The AIUR-11-150K is a highly efficient fixed inductor from AIUR. It provides low DC resistance, wide range of inductance values, and excellent temperature characteristics. It is suitable for applications such as snubbers, precision filters, and power supplies. Its working principle takes advantage of Faraday’s law, wherein an alternating current is applied to the component and the changing electric field creates a magnetic field, resulting in a Back EMF. This, combined with the DC resistance of the component, produces an inductive reactance which is a measure of the opposition to AC current.
