Fixed Inductors

A fixed inductor is an electrical component that stores energy in its magnetic field. It is one of the most commonly used components in a variety of applications. In the context of electronics, a fixed inductor absorbs and releases energy in its magnetic fields.The IR02BH270K is a fixed inductor that serves as a storage component for electric power and can be found in various electronic products including mobile phones, monitors and computers. In basic terms, it is a flat spiral made of wire which is wound around a core material such as ferrite. The core material gives the inductor a high energy storage capacity.

Applications

The IR02BH270K is largely used in a wide range of low-frequency power supply circuits. The components are designed for use with DC power terminals and are highly effective for filtering AC from a DC supply. In making an electronic circuit board, the IR02BH270K ensures there is no voltage ripple at any stage in the circuit, which could cause damage to other components or interfere with power output.The IR02BH270K also serves as a buffer for power supplies. It is used to regulate and enable energy to be stored in a capacitor before being released, depending on the electrical power requirement. This prevents abrupt voltage changes that can lead to instability in the circuit.The IR02BH270K is also popularly used in electronic equipment as a frequency dividing network that divides high frequency signals into an alternating current (AC) or variable signal. It can also be used to amplify weak radio signals and is specifically designed for use with energy management systems where energy conservation is a priority.

Working Principle

The IR02BH270K operates on the principle of an inductor which operates when there is a differential effect between the self-inductance and the magnetism of the component. It has inductance which is measured in henries (H). The inductance is related to the amount of current flowing through the wire.When direct current (DC) flows through the coil of the inductor, the component’s magnetic field builds up and stores stored energy. The stored energy is then released back into the circuit. This is done when circuit load reduces, which causes the current in the coil to reduce and the stored energy to dissipate.When alternating current (AC) is applied to the inductor, its core stores alternating magnetic flux. This fluctuating signal is displaced and usually in 90 degrees out of phase when compared to the input signal. Therefore, when AC has a time varying electric field component, an electromagnetic field component is generated which produces an induction current in the windings.

Conclusion

The IR02BH270K is a versatile fixed inductor that is found in a wide range of electronic products. It serves as a storage component for electrical power that ensures there is no voltage ripple in the circuit and also functions as a frequency dividing network. Operating on the principle of an inductor, when DC or AC is applied to the component, the magnetic field builds up and the stored energy is released back into the circuit.
