IR04BH471K

Fixed inductors are a type of inductor designed to maintain a fixed level of inductance for a given applied physical and electrical configuration. They are widely used in circuits and equipment like motors, transformers, coils, and generators. Among the fixed inductors is the IR04BH471K, which has very specific applications and working principles.

Applications

The IR04BH471K is a standard type of radial-leaded plastic film coated inductor. This type of inductor is applicable to power supplies, as it can handle higher DC current than others and filter out bigger noise levels. Its resistance to high voltage is also very good.

The IR04BH471K is perfect for wide temperature range applications, as its operating temperature range is -40-105 degrees Celsius. It is suitable for use in automotive electronics, consumer electronics, and medical electronics, among others.

The inductor also has impressive electrical characteristics, including a resistance of 10 Ohms, an inductance of 470μH, and a DC current rating of 1.68 Amps. Its insulation system is very effective, having a temperature class of B. Its frequency response is also excellent, reaching up to 1MHz.

Working Principle

The working principle of the IR04BH471K is simple but effective. This type of inductor is designed to create a resistance to changes in the current in a circuit, by storing electromagnetic energy and releasing it back into the circuit in the form of a magnetic field. This process creates a counter-EMF, or back EMF, that hinders current flow and provides stability to the circuit.

The inductance of the IR04BH471K is determined by the physical size and shape of the inductor, as well as the core material used in its construction. It is also affected by the number of turns and the type of winding used. The DC current rating is determined by the amount of heat sinking available to the inductor.

The resistance of the inductor is closely related to its inductance. As the DC current flows through the inductor, a small amount of this current is lost due to the resistance, which is then manifested as heat generated by the inductor. This is why it is important to keep the inductor operating within its specified temperature range.

Conclusion

The IR04BH471K is a type of fixed inductor designed for use in a wide variety of electronic and electrical applications. It is suitable for high voltage, wide temperature range applications, and has excellent electrical characteristics and frequency response. Its working principle is simple but effective, as it creates a resistance to changes in current and provides stability to the circuit.
