S0402-27NF1C

Fixed Inductors

Fixed inductors are one of the different kinds of electrical components. They are designed to produce a steady, unchanging magnetic field for a given current. In this article, we will analyze the S0402-27NF1C and discuss its application field and working principle.

What is S0402-27NF1C?

S0402-27NF1C is a fixed inductor series produced by TDK Corporation (Japan). It is in the 0402 size and 0.2μH inductance range. This series offer high current tolerance, low DC resistance, and high operating temperature (up to 125°C). Moreover, in this series, it features anti-clockwise terminals for normal polarity and clockwise terminals for reverse polarity.

Application Field of S0402-27NF1C

S0402-27NF1C is mainly used in automotive, communications, and consumer electronics applications. In automotive, it is primarily used in power converters, power supply lines, and in AC parts. In communications, they are used as filters in portable radios, mobile phones, power amplifiers, and similar wireless devices, where it helps to reduce interference between the signals. Similarly, in consumer electronics, it is used in electric guitars, TVs, DVDs, and other electronics where it is used to filter and shield the signals form external electromagnetic waves and noise.

Working Principle

Fixed inductors use the electromagnetic principle to carry. When electric current flows in a wire, an electric field is created around it in a circular fashion. When this current encounters a core of a ferromagnetic material, the electric current is induced in the core and creates a circular magnet field side by side. This creates an opposing magnetic field which maintains the current flow. This is known as Faraday’s law and it explains how inductors work.

The S0402-27NF1C series of fixed inductors consists of two windings. The primary winding is made of metal and it is responsible for creating the inductance. The second winding is the core, which is made out of ferromagnetic material and it allows the induction of another current. This combination is what allows inductors to work properly and perform their intended functions.

Conclusion

In summary, fixed inductors are electrical components which use the principle of Faraday’s Law to produce a steady magnetic field. The S0402-27NF1C series of fixed inductors from TDK Corporation are designed for high current tolerance, low DC resistance, and high operating temperatures. They are mainly used in automotive, communications, and consumer electronic application, as they are used to filter and shield signals from external electromagnetic waves and noise.
