Fixed inductors, also known as chokes, are electrical components that are usually found in various electronic devices and circuits. They are passive components that store energy in the form of a magnetic field. They are commonly used in filtering applications, such as in power supplies, as well as in radio frequency (RF) circuits. They are also used in low-frequency circuits, such as audio and low-frequency amplifier filters.Fixed inductors are available in a range of sizes and types, from tiny surface-mount components to large, heavy-duty chokes. One of the most popular types of fixed inductors is the SP1812R-124H. This type of inductor is a non-polarized, radial-style, fixed inductor with a rated current of 1.2 amps and an inductance of 20 mH (20 milliHenries). It is constructed using an enameled copper wire, a ferrite core, and a molded plastic body.

The SP1812R-124H is typically used in a wide variety of electronic applications, such as AC-DC power supplies, DC-DC converters, switching regulators, radio receivers, and amplifiers. It is well-suited for use in low-frequency circuits, as it has good frequency response characteristics. This inductor offers excellent linearity, meaning it will maintain its inductance value over a wide range of currents. It is also low in noise, making it well-suited for applications where noise-free operation is essential.

The SP1812R-124H inductor works on the principle of electrical induction. When the current flows through the inductor, a magnetic field is created, which induces an opposing voltage into the coil. This phenomenon is known as “back-EMF” and is the basic principle behind the operation of an inductor. The inductance of the SP1812R-124H is a function of the amount of conductive material, the size of the core, and the number of turns in the coil.

The working current that can be handled by the SP1812R-124H will depend on the power ratings of the specific inductor, as well as the amount of current it sees during operation. As a general rule, it will be able to handle currents up to around 1.2 amps. As the amount of current increases, the temperature of the inductor will also increase. If the temperature gets too high, it can cause the inductor to fail prematurely. Therefore, it is important to ensure that the inductor is not operated beyond its specified temperature ratings.

The SP1812R-124H is a robust, reliable, and economical choice for a wide range of applications. It is ideal for applications where high performance is required, such as those found in power supplies, amplifiers, and switching regulators. Its low noise characteristics also make it suitable for use in noise-sensitive applications. The SP1812R-124h is also easy to assemble, making it a popular choice for those looking for an efficient and cost-effective solution.
