Fixed inductors, commonly referred to as coil or chokes, are self-supporting inductor components that achieve a fixed reactance value for a given frequency or current. This component is a widely used passive device in electronic circuits and is found in a wide variety of applications, including power, automotive, medical, test and measurement, audio and video, telecommunications, consumer, military and automotive. One of the most popular fixed inductors is the IR04BH100J. This article will discuss the application field and working principle of the IR04BH100J.The IR04BH100J is an inductor designed for high frequency applications such as power factor correction, EMI/RFI filtering, and voltage stabilizing. The inductor is constructed of a copper wound core, pre-tinned copper end caps and a power rating of 4A. It offers inductance values of 4.7µH, 9.6µH, 13.4µH, 18µH, 22µH and 40µH. It has a very low DC resistance of 0.18Ω and an operating temperature of -25℃ to +125℃.The application field of the IR04BH100J is broad and can be used for many applications requiring stable voltage levels. For example, it can be used in power supply circuits for voltage regulation, EMI/RFI suppression, power factor correction, and voltage shifting. In addition, it is also used in automotive applications. The IR04BH100J is often used in EMC designs, as the inductor reduces high-frequency electrical interference created by other electrical components in the circuit.The working principle of the IR04BH100J is based on the principle of electromagnetic induction. Electromagnetic induction is the phenomenon in which an electric current is induced in a conductor by a varying magnetic field around it. The IR04BH100J consists of a thin copper wire wound around a magnetic core material such as ferrite. The wire is then connected to two external terminals called “ends.” When a varying current passes through the copper wire, the electric field created by the current interacts with the magnetic field of the core material, inducing an electric current in the wire. This induced current is known as an “induced current” or “inductance.”The induced current in the IR04BH100J is greater when the applied current in the coil is greater, allowing the component to act as a voltage stabilizer in applications where a stable voltage is needed. It also provides improved power factor correction, as the current variation caused by an increase in load can be compensated for. The inductance also helps to reduce the level of high frequency electrical interference generated by other components in the circuit, ensuring good operation of the electronic system.To sum up, the IR04BH100J is a versatile fixed inductor suitable for a wide range of applications. It is used in power supply circuits for voltage regulation, EMI/RFI suppression, power factor correction, and voltage shifting. The working principle of the component is based on electromagnetic induction, which creates an induced current when a varying current passes through the component’s copper winding. This current is used to create a stable voltage in applications where a stable voltage is needed, and also provides improved power factor correction.
