Fixed Inductors

Inductors are a type of component used in electronic circuits that store and release energy in the form of an electric current. They play an important role in many circuit applications, including oscillators, filters, power supply circuits and frequency-dependent signal transmission circuits. In particular, fixed inductors are designed to provide a predetermined and constant inductance value regardless of fluctuations in circuit parameters.

CAL45VB222K Application Field and Working Principle

The CAL45VB222K is a fixed inductor with a rated inductance of 2.2 mH. It has a maximum DC current rating of 0.9A and a saturation current rating of 3.08A. It operates in a temperature range of -40°C to +105°C.

The CAL45VB222K is usually used in RF and audio circuits in applications such as low-cost IF circuitry, voltage regulation and auto gain control. It has excellent temperature stability and low hysteresis compared to other fixed inductors on the market. Additionally, it can be used in interference suppression circuit applications, such as for setting the resonance frequency of notch filters and suppressors.

The CAL45VB222K’s working principle is simple. It consists of a coil of insulated copper wire wrapped around a ferromagnetic core. When a current is passed through the coil, it creates a magnetic field around the core which induces an opposing current of the same size in the coil. This opposing current is called the inductance. The amount of inductance produced depends on the number of turns in the coil, the material used for the core, and the current flowing through the coil. The more turns there are, the greater the inductance.

The CAL45VB222K’s inductance values can remain relatively constant, even when the applied voltage or current changes. This makes the device suitable for applications where inductance value accuracy and stability are important.

In summary, the CAL45VB222K is a fixed inductor designed to provide a predetermined and constant inductance value regardless of fluctuations in circuit parameters. It is commonly used in RF and audio circuits, such as in low-cost IF circuitry, voltage regulation and auto gain control, as well as interference suppression circuit applications. Its working principle is based on that of a coil of copper wire wrapped around a ferromagnetic core and the inductance value is determined by the number of turns in the coil, the material used for the core, and the current flowing through the coil.
