Fixed inductors, also known as coils, coils, or choke coils, are passive components that are used to store energy in the electric field or magnetic field, and then release it. The LB2012T220K fixed inductors perform this function and are a type of inductive components. This inductor is often used in DC-DC converters, LED drivers, and other circuits.

The LB2012T220K fixed inductor is a 0402 size 0204 case style high current SMD inductor, with a maximum operating temperature of +125°C, a rated inductance of 220 uH and a rated current of 2A. It should be noted that the inductance value will vary with the change of current, with the temperature coefficient at 0 ± 20 ppm / °, the resistance at 0.064 Ω and the capacitance at 7.5 pF.

The LB2012T220K fixed inductor is made up of three main parts: a magnetic core, a winding around the core, and a lead frame. The material of the magnetic core is MPP, the winding material is copper wire, and the lead frame is made of copper.

The magnetic core of the LB2012T220K fixed inductor is usually composed of ferrite and powdered iron and by varying the shape and material of the core, the inductance of the inductor can be adjusted. As the current increases, the generated magnetic field more strongly interacts with the magnetic core, inducing a greater voltage drop. As the current decreases, the magnetic field weakens, reducing the induced voltage drop.

The windings of the LB2012T220K fixed inductor are invariably copper wire and form a single loop. The windings are wound around the magnetic core and the number of turns determines the inductance. The windings are usually insulated to prevent an electric arc from forming when a large current passes through.

The lead frame of the LB2012T220K fixed inductor is also made of copper, and is attached directly to the windings. It is connected to the outer circuit and provides a path for electrical current to reach the windings.

The LB2012T220K fixed inductor is used in many applications. One such application is DC-DC converters, where the inductor can provide a constant voltage to the circuit. The inductor also acts to regulate the current flow through the circuit, ensuring that the voltage does not go beyond the safe range. The LB2012T220K fixed inductor is also used in LED drivers to provide the necessary current while ensuring that the voltage remains within a safe range.

In summary, the LB2012T220K fixed inductor is a useful and versatile inductive component. Its ferrite core, windings, and lead frame are able to work together to regulate voltage and current while preserving the inductor’s electrical properties. This makes the LB2012T220K fixed inductor a popular choice for circuit designs of all kinds.
