Fixed Inductors

A fixed inductor is an electrical component which stores energy in the form of a magnetic field. It is also known as a choke, a coil, or an induction coil. An inductor can be used to create a filtering effect by reducing the amount of energy which passes through a circuit. It can also be used for coupling, impedance matching, and tuning.

The IR04BH330K is a fixed inductor that is designed for applications that require an inductor with high current and low inductance. It is an unshielded wire wound inductor and has a rated current of 3.0AMP and a peak current of 4.5AMP. The inductance range is 3.3uH to 330uH, with an operating temperature range from -25 to 105°C. The IR04BH330K is available in a compact size package, and is used in many applications, such as industrial power supplies and power distribution.

Working Principle

The basic working principle of a fixed inductor is based on Faraday’s laws of induction. According to Faraday’s law of induction, a change in flux density induces a voltage. When a conductor is placed in a changing magnetic field, an EMF (Electromotive Force) is induced in the conductor. This EMF is proportional to the rate of change of flux, which is known as inductive reactance.

The IR04BH330K works in the exact same way. When an AC current is passed through the inductor, a changing magnetic field is created which in turn induces a voltage across the inductor. The induced voltage is proportional to the rate of change of the magnetic field and the inductance of the inductor. The inductance of the IR04BH330K is 3.3uH to 330uH which helps to create a filtering effect, which can be used for impedance matching or coupling in the given application.

Application Field

The IR04BH330K is used in many different application fields, such as industrial power supplies and power distribution. It is used in these applications due to its low inductance and high current capabilities. The low inductance is beneficial because it helps reduce the amount of energy which passes through a circuit and creates the desired filtering effect. The high current feature is beneficial because it allows the use of higher currents in certain circuits.

Another application that the IR04BH330K is used for is in audio applications. It is often used in audio amplifiers, because the small size of the inductor enables the audio to be amplified within a small space. The low inductance also helps to enhance the sound quality by reducing any magnetic interference.

The IR04BH330K is also used in DC/DC Converter applications, because of its low inductance and high current capabilities. The low inductance helps to reduce the amount of energy which passes through the circuit and the high current allows the use of higher current levels. It is also used in wireless applications, because the inductor can help reduce electromagnetic interference which can interfere with the signal.
