Fixed Inductors

Fixed inductors are electronic components used to restrict or store energy in a static form. They are generally composed of a coil of wire wrapped around a ferromagnetic core, with the windings connected in either parallel or series depending on the type of inductor. As a component, fixed inductors are widely used in various industries and applications. One of the most popular is the SC1206-R22. In this article, we will discuss its application field and working principle.

SC1206-R22 Application Field

The SC1206-R22 is a precision surface mount inductor solution for a variety of applications, mostly related to audio/video signal processing, or wireless communication. It is used to filter out frequency-based noise and unwanted signals in circuits, while providing a certain degree of signal amplification. Its performance is especially suited for high-bandwidth applications such as:

• Imaging
• Audio/Video
• Radar
• Communication
• Automotive

The SC1206-R22 has been designed to provide superior filtering capabilities while having small footprints and great form factor, allowing it to be installed in dense components, like 3D-printed electronics or miniaturized circuits.

SC1206-R22 Working Principle

At the basic level, fixed inductors work in this manner: when electric current passes through a conductor (the coil of wire), it creates a magnetic field. This magnetic field generates an induction voltage, which opposes the original current. In other words, the induced voltage works against the original voltage, thus limiting the amount of current flowing through the conductor. This is how a fixed inductor works.

When it comes to the SC1206-R22 specifically, it operates in two modes: static and dynamic. In static mode, the inductance of the inductor remains constant as the applied signal changes. This makes it suitable for filtering out interference and unwanted frequencies at constant amplitude. In dynamic mode, the inductor can be used to amplify a signal, as the applied signal increases the inductance value, increasing also the amount of current it can handle.

In general, fixed inductors like the SC1206-R22 are ideal for a wide range of applications, as its size allows it to fit on almost any circuit. Its superior filtering and shielding capabilities are also great for applications in which noise and interference need to be blocked out and amplified signals cut through.
