Fixed Inductors

Fixed inductors are core components used to directly store energy in the form of a magnetic field in an electrical circuit. They are widely used for filters, signal processing, power supply circuits, and other circuits needing inductance.LQH43NN4R7K03L fixed inductors are among the most widely used, providing resistance to changes in current, great power protection, and excellent frequency characteristics.

LQH43NN4R7K03L Application Field

Specifically, LQH43NN4R7K03L fixed inductors are used for various types of filters, especially for audio equipment, inverters, and other digital electronic circuits. They are an ideal choice for low-noise high-frequency resistance applications due to their high inducerance tolerance, small size, and low cost. The LQH43NN4R7K03L has a wide operating temperature range from -40°C to +85°C.

The maximum current handling of this inductor is 2.20 A, a good level for many applications and it can create an inductance of 3.3μH with a small tolerance down to ±0.3μH.

LQH43NN4R7K03L Working Principle

The LQH43NN4R7K03L utilizes the principle of induction to create a magnetic field around a transformer core when carrying a current.This inductor is wrapped with a copper wire and then placed in a specially designed high-performance magnetic shield, which considerably reduces the effect of the outside electromagnetic field on it.The inductor can also be designed to have specific features to reduce impedance, current ripple, and resistance.

In a steady state, the inductor\'s magnetization will remain constant, leading to no losses. When a change in the current input occurs, the inductor\'s magnetization will slowly adjust. Because the inductor has inductance, the current can be limited by the ratio of the inductance and resistance of the circuit. This means that the inductor acts as a filter against rapid changes in current.

When in use, the copper wire winding on the inductor creates a magnetic field that contains energy. This energy stored in the inductor can be used to supply power when needed. In addition, because the inductor provides resistance to voltage changes, it can act as a buffer against spikes or surges in the supply voltage.

The LQH43NN4R7K03L fixed inductors provide excellent performance and reliability, a wide operating temperature range, and a high power capability. They can handle high frequency operating conditions with excellent frequency characteristics and provide great protection against changes in current, making them a great choice for audio processing applications and other digital electronics.
