Fixed Inductors

Inductors, commonly referred to as coils, chokes or solenoids, have been known for centuries and have been used in various applications. A fixed inductor is an electrical component made up of a coil of wire, typically with a core of metal, used to store electrical energy and produce low-frequency magnetic fields. This type of inductor has been around for many years, and today they are used in a variety of electronics applications, such as motors, power supplies, and audio amplifiers.The S1210R-472H is a type of fixed inductor, first introduced in 1990 by a company called SPIRE. It is a relatively small component, measuring only 10mm in length, and 4mm in width, and features a maximum frequency of 250kHz. The inductance of the S1210R-472H is 4.7uH, and its DC resistance is 12mΩ. The S1210R-472H is also available in a variety of package sizes and lead lengths, allowing it to be used in many different circuit configurations.The S1210R-472H is a popular fixed inductor used in many applications, such as filtering, switching regulators, switch-mode power supplies, electric vehicles, and microcontrollers. It is also often used in antenna applications to improve performance, and in audio amplifiers to reduce interference. The S1210R-472H is well-suited to these applications because it has wide temperature range (-40°F to +85°F) and can handle high currents (from 0.1A to 1.0A).In terms of its working principle, the S1210R-472H behaves like all other inductors. When it is supplied with an alternating current, its core stores energy in the form of a magnetic field and then releases it as a current. This process occurs through a number of inductive reactions, in which the coiled wire of the inductor creates a small magnetic field, which then propagates through the core of the device, producing an electromagnetic field. The inductive reaction in the S1210R-472H creates an alternating current in the form of an oscillation, which is often used to power digital circuits.In addition to its use in audio amplifiers, electric vehicles, and antenna applications, the S1210R-472H can also be used in power filters, which help to reduce unwanted noise and improve the quality of audio signals. They are also often used in power supplies and switching regulators, as they can help to regulate the flow of electricity and reduce power losses.Overall, the S1210R-472H is a versatile and reliable fixed inductor, perfect for a wide range of applications. It is available in multiple package sizes and lead lengths, allowing it to be used in a variety of circuits. Additionally, it has a wide temperature range and can handle high currents, making it well-suited to electronics and audio applications. Moreover, the S1210R-472H has a relatively low DC resistance, and is able to store and release energy in the form of oscillations, making it ideal for powering digital and other electronic circuits.
