Fixed Inductors

A fixed inductor, or inductor, is an electronic device that stores energy in a magnetic field. It can be used in a variety of applications, such as for voltage control, filtering, and modulation, but is most commonly used in power electronics or power supplies. As with all passive components, it has no moving parts and does not generate energy.

LBR2012T101KV Application Field and Working Principle

LBR2012T101KV fixed inductors are widely used in many applications, such as switching power supply, power electronics and communications equipment, battery powered equipment, etc. The inductor is composed of two components: a coil of copper wire wound around a core of ferromagnetic material, and a built-in magnetic shield. The coil carries a direct current; this current causes a magnetic field in the core which then induces a current in the wire winding(s).

The magnetic shield integrated in the enclosure prevents the magnetic field from emitting from the inductor, which would otherwise disrupt the operation of other components in the system. The magnetic shield ensures that the cross sectional area of the inductor is shorter than that of the coil and shields the magnetic field from direct interference.

Depending on the nature of the application, the inductor can have a single-layer or a multi-layer coil winding. For higher inductance values, the core is usually made of ferrite (a polycrystalline oxide ceramic material). For very high inductance values, there are also air-core inductors available. Air-core inductors are usually used for semiconductor control circuits and radio frequency circuits.

The performance of LBR2012T101KV fixed inductors depends mostly on the inductance value and the saturation current. The inductance value should be kept as low as possible; it is usually given in units of microhenrys (µH). The saturation current is a measure of the maximum current the inductor can handle without permanent damage. It should also be kept as low as possible, since excessive current can heat the inductor and cause permanent damage.

In addition to the core material, the inductance value of an inductor also varies with the number of windings. The windings can be arranged in different types, such as single-layer, series-layer, and crossed-layer. The inductance value is greater with more windings and a larger cross-sectional area of the wire. If needed, a shield can also be used to reduce the leakage of the magnetic field.

Overall, LBR2012T101KV fixed inductors are a widely used type of passive component with numerous applications. Its main function is to store energy in a magnetic field, and its performance depends mainly on the inductance and saturation current values. In addition, the way the windings are arranged and the core material also affects the performance of these inductors.
