Fixed Inductors

A fixed inductor refers to an inductor of a specific size and design that has a certain degree of inductance and is often used in the circuit to provide protection. As an electronic component, the CAL45TB222K is a high performance hybrid fixed inductor from Johanson Technology Inc. It is an essential part of application for choke or filter and it is designed to provide a wide range of current carrying and thermal ratings for high-density applications. In this article, we will focus on the application field and working principle of CAL45TB222K.

Application Field

CAL45TB222K is suitable for a variety of high frequency application needs, such as electromagnetic interference (EMI) suppression, radio frequency interference (RFI) suppression, and powerline transient surge suppression. It is an ideal component in applications exposed to high voltage and high current, and it can effectively reduce electrical noise, protect the circuit from damage, and maintain signal integrity. In addition, it is applicable for voltage and current isolation. The CAL45TB222K can also be used on low power on/off circuits, button/switch circuits, low voltage level shifters, AC/DC converters, power amplifiers and power supplies.

Working Principle

The working principle of CAL45TB222K is based on Faraday\'s Law of Induction. This law states that the emf induced in an electrical conducting loop is equal to the time rate of change of the magnetic flux linked with the loop. CAL45TB222K is made of a ferrite core wound by a copper wire, with its core size ranging from 1210 to 3310. When an external voltage is applied to the device, the resulting current flow inside the copper wire creates a magnetic field around the core. This magnetic field is what induces a voltage into the device, which can be used as an output.

When the external voltage is removed, the magnetic field collapses, and the induced voltage is removed. The ferrite core of CAL45TB222K has an inductance ranging from 1µH to 220µH, so this device can store electrical energy when a voltage is applied to it and release it when the voltage is removed. This stored energy is returned to the circuit in the form of an output voltage.

The outstanding features of CAL45TB222K make it a key component of a variety of high-frequency electronic systems. With its excellent performance and high power handling capabilities, CAL45TB222K is leaving no room for failure, thus making a lasting contribution to the quality of the working environment.
