Fixed inductors are components with inductance that typically stay unchanged, even when subjected to varying current. The SC414MF-120 is a fixed inductor that offers a wide range of applications in different industries. This article will go over its working principle, as well as its associated application fields.

The SC414MF-120 consists of a tinned copper winding around a non-magnetic core base material composed of ferrite or powder iron. This device produces a magnetic field that is determined by the value of inductance, which is usually specified in Henries varying from 0.1uH to 10uH. Depending on the physical design of the core material, the actual inductance may vary significantly from room temperature to other working temperatures.

The primary working principle of the SC414MF-120 is based on Faraday’s law of induction, which states that a changing magnetic field will induce a voltage in a nearby circuit. When an electrical current flows through the copper winding of the SC414MF-120, it creates a magnetic field. Any changes in the current will generate a changing magnetic field, which then induces a voltage in a nearby circuit.

The SC414MF-120’s application field is vast, as it can be used as an inductor or a filter in a wide variety of designs. This device can be found in various audio, automotive, aerospace, and telecommunications applications. In audio equipment, the SC414MF-120 works to reduce movement in the speaker voice coil, improve signal-to-noise ratios, and protect against high-voltage spikes. In the automotive industry, it is used to filter and protect automotive audio systems. In the aerospace and telecommunications sectors, it is employed for filtering AM radio signals, antennas, cordless phones, cell phones, and even printed circuit board protection.

Aside from its numerous applicable fields, the SC414MF-120 is also beneficial and popular for its added features, which are temperature resistance and frequency characteristics. Commonly found in professional audio settings, these added features make the SC414MF-120 much more versatile. Its frequency characteristics depend on the inductance of the inductor and the core material; models with higher inductance require cores with higher frequency. Temperature resistance is determined by the type of core material used; ferrite-based inductors offer good temperature stability, while powder iron-based inductors have better stability at extreme temperatures.

In conclusion, the SC414MF-120 is a useful fixed inductor designed to improve and protect audio applications in several industries. It is equipped with high-performance features such as temperature resistance and frequency characteristics, and comes in a range of inductance values from 0.1uH to 10uH. Its application fields include automotive, audio, aerospace, and telecommunications, making it a versatile and beneficial component for various designs.
