Introduction to Fixed Inductors

A fixed inductor is a type of electrical component that stores energy in the form of a magnetic field. They are used to create oscillators, filters, tuned circuits, and even radio antennas. Unlike variable inductors, fixed inductors are made to a predetermined inductance, meaning their value of inductance does not change over time. Because of this, they’re often used in circuits where the current needs to be maintained at a certain value or frequency.

Fixed inductors are typically comprised of wire tightly wound onto a core of metal, ceramic, or ferrite material.

Types of Fixed Inductors

There are a variety of fixed inductor types available, each designed to meet the needs of a particular use. Common types of fixed inductors include toroidal, chip, surface mount, through-hole, and multiple winding inductors.

LHL13NB470K Fixed Inductor

The LHL13NB470K fixed inductor is a chip type, designed for use on printed circuit boards. It has a rated inductance value of 470 nanohm. The LHL13NB470K is also RoHS compliant, meaning that it meets the European Union standards on the restriction of hazardous substances in electronic components.

Application Field

The LHL13NB470K is most commonly used in DC-DC converter applications, such as those found in computers and embedded systems. It can also be used in peak current wave shaping applications, as well as in the resonant stage of SMPS power supplies. Other applications include DC inductor-type drivers, RF-to-DC converters, and EMI suppression.

Working Principle

The working principle of an inductor is based on Faraday’s Law of Induction. When an electrical current passes through the coil of an inductor, it creates a magnetic field. This magnetic field then stores energy in the form of a magnetic field, which can be used to create an oscillating electrical current.

The amount of stored energy in the magnetic field is determined by the inductor’s inductance value. This value is generally fixed and does not change over time.

Conclusion

The LHL13NB470K fixed inductor is a chip type inductor commonly used in DC-DC converters and a variety of other applications. It is RoHS compliant and has a rated inductance value of 470 nanohm. Its working principle is based on Faraday’s Law of Induction, in which an electrical current passing through a coil creates a magnetic field, which in turn stores energy in the form of a magnetic field.
