Fixed Inductors

Inductors, also known as coils, are an important form of component in electrical and electronic equipment. They can be used in a variety of applications, such as power supplies, signal conditioning, radio communications, and more. The most common type of inductor is a fixed inductor, which is designed to have a fixed inductance that does not change with time or frequency. One example of a fixed inductor is the CR43-1R0MC.

The CR43-1R0MC is a radial leaded, surface-mount power inductor with a rated maximum current of 4.5A. It is constructed out of a ferrite core with a copper wire winding. The inductor has a low DC resistance, allowing it to handle higher current compared to other types of inductors. This makes the CR43-1R0MC suitable for use in high-power applications, such as energy storage devices or power converters.

The CR43-1R0MC is typically used in DC/DC converter applications. The inductor helps to regulate the current flowing through the circuit. The value of the inductor can be adjusted by using different combinations of winding turns. This allows the converter to be tailored to the specific load and output power requirements of the system.

The working principle of the CR43-1R0MC is based on Faraday’s Law of Induction. As current flows through the inductor, it creates a magnetic field. When the current changes, the magnetic field associated with the inductor changes. This creates an electromagnetic force in the opposite direction of the current, which helps to stabilize the voltage output of the circuit.

The CR43-1R0MC is a small and lightweight inductor, making it suitable for space-limited applications. It has a low profile, allowing it to fit in tight spaces. The inductor also features a high temperature rating of up to 125°C, making it suitable for use in high-temperature environments. Additionally, the inductor is RoHS compliant, making it an environmentally-friendly choice.

Overall, the CR43-1R0MC is an ideal choice for a variety of applications where a fixed inductor is required. It is small and lightweight, and can handle high current. The inductor also has a very high temperature rating, and is RoHS compliant. It is typically used in DC/DC converter circuits, where its fixed inductance helps to regulate current and stabilize the voltage output.
