Fixed inductors are widely used in modern electronic circuits, and this type of electronic component is designed to store electrical energy. The IR04BH221J is a fixed inductor from Hongfa Electronic Co. Ltd., and is commonly used in the control of electrical devices. This article will discuss the application field and working principle of the IR04BH221J.

The IR04BH221J is a 4-terminal, three-layer, sealed wire-wound inductor with has a rated current of 7 amps and a rated inductance of 221mH. It has a tolerance of ±5%, and its inductance can be used over a wide frequency range of 100kHz to 100MHz. It features a high ripple current, low DCR, and excellent temperature performance. The unit is sealed with an epoxy-based coating for protection from external elements.

The IR04BH221J is a versatile fixed inductor, and is suitable for a wide range of applications. It is commonly found in power supplies, switching power supplies, LED/LCD display controllers, automotive electronics, motor drivers, and other electronic device controls. Due to its high current capacity and low DCR, it can also be used in high-efficiency switching converter applications.

The IR04BH221J works by using electromagnetic induction to store electrical energy in the form of inductance. This electrical energy can then be used to regulate current flow. The inductor consists of a core that is wound with insulated wire. As current flows through the wire, it produces an electromagnetic field that is captured and stored in the core. The electromagnetic field acts as a filter, increasing or decreasing the amount of current passing through the inductor, depending on the specific application.

When power is applied to the terminals of the IR04BH221J, a current is created which then creates an electromagnetic field. This field creates a varied current, depending on the amount of current passed through the wire. When the current passes through the core, the magnetic field changes, thus varying the inductance. This change in inductance in turn affects the current flow through the circuit.

The IR04BH221J is a fixed inductor with a wide range of different applications. It is able to regulate current flow to electronic devices, allowing them to remain stable and deliver consistent performance. By controlling the flow of current, the IR04BH221J prevents damage to components and increases efficiency. Its high tolerance, low DCR, and excellent temperature performance make it highly effective in its application.
