The CAL45TB820K-1K is a fixed inductor, manufactured by Nippon Chemi-con. It is part of their CALT series of fixed inductors, which have very high operating temperature ratings.

The CAL45TB820K-1K is made up of an integrated ceramic core, a copper wire winding, and a nickel-plated enclosure. This fixed inductor has a rated current of 3.75A and a inductance value of 820uH ± 5%. It has an operating temperature range of -55°C to +120°C.

Given its components and parameters, the CAL45TB820K-1K has a multiple applications and makes it suitable for use in a wide range of fields. It can be used for current smoothing in DC to DC converters, as well as being used in power supplies, LCD TV systems, and car audio systems. It can also be used in selective frequency tuning in audio systems and for harmonic filter circuits.

The CAL45TB820K-1K works according to the basic principles of electromagnetism. When an electric current is applied, it induces a magnetic field around the inductor. This magnetic field then causes a back electromotive force, which resists the change in current. As a result, the electrons have to ‘jump’ over each other and a voltage rise is produced.

This voltage rise is referred to as ‘inductance’ and is measured in consideration of the number of turns in the winding and the permeability of the core. In the case of the CAL45TB820K-1K, the inductance value is 820uH ± 5%, meaning that the back EMF is 820uH ± 5% for every 3.75A of current.

To ensure maximum performance, the CAL45TB820K-1K requires precise placement of its core and windings, and this is achieved by using a proprietary manufacturing technique. The inductor is then tested using a high frequency, high voltage pulse to check for any resonance that may occur. The CAL45TB820K-1K is then coated with a protective shell, which ensures that the inductor has a long lifespan.

In conclusion, the CAL45TB820K-1K is a versatile fixed inductor, suitable for use in a variety of devices and system. Its components and parameters provide a 820uH back EMF for each 3.75A of applied current, while its high temperature resistance allows it to be used in a wide range of applications.
