Fixed Inductors

Inductors are components used in electronics, usually consisting of insulated wire wrapped around a magnetic core of iron or ferrite. When a current is applied to the insulated wire, an electromagnetic field is formed in the form of a concentrated loop around the inductor, creating an inductance. Fixed inductors have a fixed inductance value that is not adjustable.

The LAL03TB3R9K series is a type of fixed inductor designed for high frequency applications. It is a surface mount device (SMD) designed to keep electrical current and signals from interfering with one another.

Application Field

The LAL03TB3R9K series is a popular choice for various high frequency electronics applications. It is well suited for use in switch mode power supplies, radios, and other applications subject to strong magnetic fields. It is also suitable for use in automobiles, communication systems, and other applications requiring the prevention of electrical or electromagnetic interference.

Working Principle

The LAL03TB3R9K series has a unique working principle due to its use of ferrite core. Ferrite is a material that has a high magnetic permeability, meaning it can absorb large amounts of energy from the magnetic field created by the inductor. This results in a high inductance rating. The coil design of the inductor also helps to increase the inductance. The high inductance rating enables the inductor to provide efficient power conversion, while suppressing noise in high frequency fan applications.

In addition to its higher inductance rating, the LAL03TB3R9K series offers some other unique features. It has an ultra-low noise level of 10μV, far lower than that of other inductors. The inductor uses a special “shielding” technique which reduces the effect of electromagnetic interference. Another distinct feature of the LAL03TB3R9K series is its small size, making it ideal for use in circuit designs with limited space.

The LAL03TB3R9K series is an ideal choice for a variety of high frequency electronics applications due to its ability to provide efficient power conversion while reducing EMI noise. Its small size and high inductance rating make it the perfect fit for many circuit designs.
