Fixed Inductors

Fixed inductors, or simply inductors, are components used in electric circuits to store energy, much like a tank stores water. They are made with copper wire or foil wound around a core, usually a soft zinc or non-magnetic steel, or with a ferrite powdered metal core. Depending on the application, inductors can be fixed in size, or able to be adjusted during operation.

Among the most popular and versatile fixed inductors is the CDRH4D28NP-560NC, manufactured by Coilcraft. This part belongs to the CDRH line of 14 inductors designed for use in switch-mode power supplies, RFI filtering, EMI suppressors, snubbers, and other devices. CDRH4D28NP-560NC has the following characteristics: self-shielding, low resistance, wide frequency range (0.1MHz - 10MHz), high saturation current (up to 6.3A) and low DC resistance (0.033 ohms). The CDRH4D28NP-560NC also offers a range of inductance values from 0.22uH to 0.81uH and can operate in temperatures of up to 150C.

Application Field and Working Principle

The CDRH4D28NP-560NC inductor is ideal for a range of applications, thanks to its reliable performance and resistance to long-term degradation. It is designed for use in high-density switching power supplies, voltage converters, power regulators, ripple filters, AC/DC converters, DC/DC converters, and power management systems. It is also suitable for some more specialist applications, such as white goods, motor controls, lighting, and UPS systems. Due to its low DC resistance and high saturation current, the CDRH4D28NP-560NC can work in high power applications and is a preferred choice for many designers.

The working principle of the fixed inductor centers on the fact that electric current creates a magnetic field when it passes through a conductor. This magnetic field has the property of storing energy in the form of a magnetic field around the conductor, allowing electric current to “flow” without generating lasting heat or other side effects. As the electric current passes through the coil, it creates inductance, a measure of the “resistance” of the circuit to the rapid changes in the electric current.

The strength of this inductance is proportional to the wire’s diameter, the number of turns, the core material, and other factors. As this inductance increases, it restricts the amount of current that can flow, allowing the fixed inductor to act as a filter for unwanted signals or as an amplifier for certain frequencies. By adjusting the number of turns or the type of core used, engineers can precisely control the overall inductance of the component.

The CDRH4D28NP-560NC has all of the features and performance characteristics necessary to make it a reliable choice for specialized applications. Thanks to its wide frequency range, low DC resistance, and high saturation current, it is able to work in high power applications with minimal degradation and excellent efficiency.
