Fixed Inductors

The LHF15BB121K is a type of fixed inductors, which is a widely used electronic component in various applications. This type of inductor is designed to store electrical energy by a magnetic field, and it is available in a wide range of BH characteristics. Its application fields and working principle will be discussed in this article below.

Application fields

Fixed inductors, including the LHF15BB121K, are widely used in many different electronic applications. They are used as inductors in switched-mode power supplies (SMPS), for filtering, smoothing and decoupling digital signals, and for impedance matching in antennas. In addition, fixed inductors can act as chokes or transient voltage absorbers, and they are also used in the design of radio receivers, high and low frequency coils, and power factor correction devices for AC/DC applications.

In some cases, the LHF15BB121K is also used as the primary winding of a transformer to provide isolation for an AC/DC circuit or for a circuit to drive a motor or solenoid. Furthermore, it is often used in audio and video systems to filter out interference, and it is also used to reduce harmonic distortion and improve the efficiency of power electronics applications.

Working principle

The working principle of the LHF15BB121K is based on the principle of magnetic induction. By passing a current through the inductor coil, a magnetic field is created around the coil and an electro-magnetic force is generated. As the current flows through the coils, the magnetic field stores energy and releases it in the form of a varying voltage when the current is changed. The amount of stored energy in the magnetic field depends on the amount of current passing through the coil and the number of turns in the circuit.

When the current flow is reversed or a new current is applied, the voltage across the inductor also changes and is related to the rate of change of current. This phenomenon is known as the inductance effect and is used to filter out noise, smooth current spikes, and create an AC/DC power supply from an AC power source. By changing the number of turns in the coils, the fixed inductor can achieve a range of inductance values to suit a variety of applications.

Conclusion

The fixed inductors, including the LHF15BB121K, are widely used in a variety of applications due to their magnetic induction principle. These inductors are used for smoothing, filtering, impedance matching and transient voltage absorption, they are also often used as part of AC/DC power supplies, audio and video systems, and radio receivers. By changing the number of turns in the coils, they can be designed to achieve a variety of inductance values to suit different applications.
