Fixed inductors play a vital role in supplying electrical energy in many applications, ranging from consumer electronics and computers to industrial and medical equipment. The LBC2012T100K is one such inductor, widely used in many circuit topologies and low-power applications. This article presents the application field and working principle of the LBC2012T100K fixed inductor.

The LBC2012T100K is a small size, high frequency shielding based fixed inductor designed primarily for use in low-power and low-output circuits, such as switching power regulators, DC-DC converters, integrated circuit packages, etc. It provides basic magnetic components such as inductance and AC blocking. It is available in five different configurations: 0.1 µH, 0.2µH, 0.3µH, 0.5µH and 1.0µH.

This fixed inductor has excellent inductor characteristics, which include low profile, high energy storage, low winding resistance, high resonance frequency, negligible core losses, and low EMI (electromagnetic interference) levels. Its dimensions are 2.05 mm x 2.05 mm x 0.99 mm, and the terminals are ready for easy installation.

The LBC2012T100K is suitable for use in circuits operating from 3.3 V to 5 V (3V to 9V). It can handle maximum current of 1.0A, with a maximum withstand voltage of 60Vdc. The inductance range is from 0.075µH to 28.6µH. It has a maximum operating temperature of 105 °C. The electrical performance of this fixed inductor is excellent, with its Q factor ranging between 30 to 70. Its self-resonance frequency is 1.0GHz.

The working principle of the LBC2012T100K is based on the principle of electromagnetic induction. It utilizes the action of a magnetic field, induced by a varying current, to induce voltage in a closed-loop path. The inductor consists of two coils that are wrapped around a ferrite core. When an oscillating current is applied to one of the coils, the magnetic field generates a circular current in the second coil, which produces a voltage that opposes the oscillating current.

This inductor can deliver higher current for a given size than other types of magnetic components, and is a cost-effective solution for low-overall-power circuits, such as those found in computers, telecom systems, consumer electronics, etc. It is ideal for connection between detachable power supply and a local load, since its low profile design allows for easy installation in tight-clearance areas. Furthermore, its high performance over temperature provides more reliable operation in harsh environments.

In conclusion, the LBC2012T100K is a high frequency shielding based fixed inductor, providing basic magnetic components such as inductance and AC blocking, suitable for use in low-power and low-output circuits, such as switching power regulators, DC-DC converters, and integrated circuit packages. It utilizes the principle of electromagnetic induction to generate an opposing voltage, and is an ideal solution for use in connections between detachable power supply and a local load. Its performance over temperature provides more reliable operation, even in harsh environments.
