1210R-471K Inductors, Coils, Chokes

Fixed Inductors

Fixed inductors are devices used in electronic circuits to store energy in the form of a magnetic field. They are also known as chokes, due to their ability to dampen high frequency noise and reduce or “choke” circuit transients. The 1210R-471K fixed inductor utilizes a ferrite core with a measurement of 12.10mm (0.476in) in width and 4.71mm (0.185in) in-depth which, with its various mounting styles, allows it to be used in many types of applications.

Application Fields

The 1210R-471K fixed inductor is found in many applications, including DC-DC converters, switching power supplies, switching regulators, Schottky barrier rectifiers, and line filters. It can also be used as an output filter component in LED ballast, lightning ballast, small power supplies, LED power, and various other electronic applications. Due to its low cost and versatile design, the 1210R-471K inductor is commonly used in high production lines.

Working Principle

An inductor is a passive electrical device that stores energy in the form of a magnetic field due to its construction and inductance. When connected to a voltage source, the inductor induces a current that lags behind the applied voltage in phase. This creates a magnetic field that increases in power with the inductor\'s inductance, allowing it to absorb energy in the form of alternating current (AC). The amount of energy stored and the rate at which it can be released depends on the voltage applied, the inductor\'s inductance, and the applied frequency.

The 1210R-471K inductor is unique in that its ferrite core allows it to have an enhanced saturation current and good high-frequency performance. The higher saturation current allows the inductor to handle large currents without significant power loss. This improves the efficiency of the circuit, as well as reducing the size of the component by reducing energy losses. Its higher rated leakage inductance also helps to improve high-frequency performance, allowing for smoother circuit transitions.

The 1210R-471K fixed inductor is an ideal choice for a wide variety of applications that require a reliable, low cost, and high performance solution. With its various mounting styles and ferrite core, it is a popular option for many industries. Its ability to handle large currents and its high-frequency performance make it a great choice for DC-DC converters, LED ballasts, power supplies, and many other electronic applications.
