Fixed Inductors: NLFV25T-220K-EF application field and working principle

Fixed Inductors are some of the most fundamental components used in a variety of electrical equipment and can be broadly classified into two categories: surface mount inductors and through-hole inductors. The NLFV25T-220K-EF is a through-hole-type Inductor/Transformer used in applications such as DC-DC power converters, filters, RF circuits, and magnetic components.

What is a Fixed Inductor?

A fixed inductor is an inductor with a constant value. It is a passive electronic component with two terminals that stores energy in the form of a magnetic field, and functions like an electrical conductor with a non-zero electrical resistance. Fixed inductors are used for a variety of different purposes, including energy storage, filtering, and DC-DC power conversion.

What is NLFV25T-220K-EF?

The NLFV25T-220K-EF is a through-hole-type Inductor/Transformer designed and manufactured by Samsung Electronics. The component has two lead pins and is a low-profile component with a height of 25mm, a width of 16.25mm, and a depth of 8.2mm. The NLFV25T-220K-EF operates at a nominal frequency of 10kHz and provides a rated power of 22W. The component has an inductance value of 220uH with a minimum DC resistance of 4.4mOhm. The NLFV25T-220K-EF is designed to operate in temperatures ranging from -40°C to +85°C.

What is the Working Principle of NLFV25T-220K-EF?

The NLFV25T-220K-EF inductor works on the principle of inductance. This is the ability of a conductor to oppose changes in current through the conductor. The inductor consists of a coil wound around a core, which can be either ferromagnetic or air. When an alternating current is applied to the inductor, a changing magnetic field is created in the core, which induces a voltage in the coil. This induced, or “back-emf” voltage, is proportional to the rate of change of the current and opposes the change. In this way, it filters out the rapid, high-frequency components of the alternating current while allowing the DC component to pass through.

Application Areas of NLFV25T-220K-EF

The NLFV25T-220K-EF inductor is a general-purpose component designed for use in a variety of different circuits and applications. It is commonly used in DC-DC power converters, where it helps to filter out the high-frequency noise while allowing the low-frequency DC component to pass through. It is also commonly used in filters to attenuate high-frequency noise. Additionally, the NLFV25T-220K-EF inductor is also used in various RF circuits and magnetic components due to its robust design and low DC resistance. In conclusion, the NLFV25T-210K-EF is a high-performance through-hole-type inductor/transformer with a rated power of 22W, an inductance of 220uH, and a minimum DC resistance of 4.4mOhm. It is commonly used in various applications such as DC-DC converters, filters, RF circuits, and magnetic components. The component works on the principle of inductance, whereby a voltage is induced in the coil when an alternating current is applied, filtering out the high-frequency noise while allowing the low-frequency DC component to pass through.
