Fixed Inductors

Fixed inductors are used in many electrical applications and are available in a variety of shapes and sizes. The CAL45TB4R7K fixed inductor is a very versatile and powerful component for many industrial applications.

CAL45TB4R7K Overview

The CAL45TB4R7K is an axial lead fixed inductor made of copper and aluminum. It has a high current rating of up to 45A, and it can handle up to 10 Ohms of resistance. The component is also moisture and humidity resistant. Its inductance ranges from 0.024mH to 0.27mH and its temperature coefficient can vary from -20 to +50%.

CAL45TB4R7K Applications

The CAL45TB4R7K fixed inductor is ideal for use in amplifiers, high-frequency power supplies, and various switching circuits. Its high current rating makes it suitable for use in power supplies and high-frequency circuits, while its moisture resistance makes it suitable for use in wet environments. Additionally, its temperature coefficient allows it to be used in temperature-sensitive circuits such as thermocouples. The CAL45TB4R7K is also well suited for use in switching applications, such as in a buck converter switch or high side and low side MOSFET switches. This inductor is also commonly used in voltage regulation circuits as a filter and in pulse width modulation (PWM) controllers.

CAL45TB4R7K Working Principle

The working principle of the fixed inductor is based on electromagnetic induction. Whenever an electrical current passes through the inductor, it generates an electromagnetic field, which creates a magnetic field that creates a voltage drop. In other words, the voltage in the fixed inductor is inversely proportional to the current passing through it.When a DC current passes through a fixed inductor, the voltage across it will drop in an oscillatory fashion (alternating positive and negative). This is called the “alternating current”, or AC, flow of electricity.The inductance of an inductor is a measure of its opposition to changes in current. This means that as the current through an inductor increases, its inductance increases as well. A higher inductance value means that more current is needed to produce a given amount of voltage. This relationship is known as the inductor’s “inductance coefficient”.The CAL45TB4R7K has a high current rating and its temperature coefficient allows it to be used in temperature-sensitive circuits, making it ideal for use in a wide range of applications. Its high moisture and humidity resistance allow it to be used in wet environments, making it an ideal choice for use in damp or wet conditions.
