Fixed Inductors: SD6030-561-R Application field and Working Principle

A fixed inductor, also known as a coil, choke, or reactor, is an electric component used to generate a magnetic field and store energy. It is widely used in electronics and telecommunications, power engineering, and other industries.The SD6030-561-R is an especially popular fixed inductor by manufacturer TDK. It is made of ferrite material and has a diameter of 6.2mm, a height of 3.5mm, and a maximum allowable operating temperature of 125 C. The SD6030-561-R’s rated DC current (IDC) range is 1.1 to 3.6A and its rated inductance range is 0.76 to 4.7uH.This versatile fixed inductor is designed for a variety of applications. It is commonly used for high-current ripple suppression, EMI noise filter applications, and power supply for logic circuits. With its low DCR and small size, the SD6030-561-R is an ideal choice for applications such as power mains, industrial, and medical equipment.Installing the SD6030-561-R is as straightforward as securing it with the included mounting screws and then soldering it into the desired circuit. Once installed, the inductor will begin to function immediately.The working principle of the SD6030-561-R is quite simple. When connected to a direct current (DC) source, the electric current travels through the wire coils. This generates a magnetic field, which induces a voltage in the same wire, which in turn creates a self-induced back electromotive force (EMF) or “back EMF”, hence the name inductor.The SD6030-561-R’s back EMF opposes the flow of DC current, which reduces the total power output. This makes the inductor a critical aspect of circuit applications such as motor control, voltage stabilization, and power supply control.In addition, the SD6030-561-R also has the ability to store energy temporarily. When the input voltage is turned off, a counter-electromotive force (CEMF) is created, which results in the energy being stored in the form of a magnetic field. This stored energy can then be released when the power is turned back on.Using a combination of CEMF, back EMF, and magnetic field generation, the SD6030-561-R offers significant protection and control for various electronic circuits. With its small size, low DCR, and high temperature rating, it is a versatile choice for a variety of applications.
