Fixed Inductors

Fixed inductors, also known as chokes, are passive electronic components consisting of a coil of wire wound around a type of core. They store energy in the form of a magnetic field. When a current is passed through them, they resist the flow of current. Fixed inductors have a range of applications in many different electrical systems.

S1210R-393K

The S1210R-393K is a popular type of fixed inductor. This particular model is a radial-lead ceramic-core ferrite inductor. It\'s designed specifically for use in switching power supplies, and is highly energy efficient. It has a rated inductance of 393mH, and a rated current of 0.25A. This particular model is also known for its fast switching speeds and low noise levels.

Application Field and Working Principle

The S1210R-393K has a variety of applications. It can be used in a variety of switch-mode power supplies, such as SMPS and AC/DC power adapters. It can also be used in PFC circuits, as well as motor control circuits. It\'s particularly useful for providing stable and clean power to small electronic devices.

The S1210R-393K works by producing a magnetic field when a current is passed through it. This magnetic field stores the energy from the current, which is then released when the current is reduced. As the current is released, the inductor produces a counter-EMF, which reduces the flow of the current through the inductor. This process allows the inductor to regulate the current in the circuit, providing a clean and stable power supply.

The inductor\'s inductance is determined by its geometry, core material, and the number of turns of wire in the winding. This can be adjusted to increase or decrease the inductance of the inductor, allowing for more precise control over the current in the circuit.

The S1210R-393K is a highly efficient and reliable inductor, making it suitable for many different applications. Its low profile, high power density, and fast switching speeds make it an ideal choice for use in applications that require clean and stable power.
