Fixed Inductors

A fixed inductor, also known as a choke, is an electronic component that primarily stores and releases electrical energy. It is comprised of a conductor, usually a coil of wire thats wrapped around a magnetic core or a ferrite core. When current is applied, a magnetic field is created, which is used to induce or create another current in a nearby conductor.

Fixed inductors are used in a wide range of electrical circuits and components. They are used in power supplies to regulate the output voltage, in high-frequency radio circuits to distribute and filter signal frequencies, and in motors to produce torque. Inductors can also be used to make filters, which are used to cut out frequencies that are deemed undesirable or unnecessary. Examples of such unwanted or useless frequencies can be electrical interference or vacuum tube noise.

The 1210R-222H fixed inductor is a good example of a classic inductor. This type of inductor has an inductance rating of 22nH at 0.5 Amps. It also has a maximum current rating of 5.5 Amps and an allowable tolerance of 20%. This inductor is characterized by its low profile SMD package, which allows for minimal space usage on PC boards.

This inductor is commonly used in applications that require high-density mounting solutions, such as automotive and aircraft electronics. In addition, the 1210R-222H is often used in power supplies, DC-DC converters, switches, and interference filters. Its low profile design is able to fit in tight locations, which makes this one of the most popular SMD inductors on the market.

The working principle of the 1210R-222H is relatively simple. When a current is applied to the inductor, a magnetic field is created, which stores energy. This energy is then released as the current is interrupted, which creates a smaller current produced at the same frequency as the original. This second current in turn induces its own magnetic field, which produces a back EMF voltage known as "regenerative feedback," which helps to keep the current as an alternating current.

In conclusion, the 1210R-222H fixed inductor is a great example of a classic inductor. Its low profile design allows for minimal space usage on PC boards, which makes it perfect for high-density mounting solutions. This type of inductor works by creating a magnetic field when current is applied, which helps to induce another current, and produces regenerative feedback. All in all, the 1210R-222H fixed inductor is a great choice for many electronic applications.
