Fixed inductors are one of the many passive components found in modern electronic circuits. They are typically made up of a coil of wire wound around a core, usually shaped like a cylinder or a bubble. This core acts as an amplifier, allowing current to flow through the coil in one or more directions depending on the geometry of the core. The amount of current that can flow through the coil is determined by the inductance of the inductor, which is usually measured in Henries (H).

The LB2518T220MV is a fixed inductor of the type known as a vertical molded inductor. This type of inductor features a vertical bobbin that has been molded around a copper wire coil. This offers a more uniform inductance as compared to traditional wound inductors. The maximum operating temperature of the LB2518T220MV is 105°C, and the saturation current is specified as 1.2A. The LB2518T220MV has a very low profile height of only 3.15mm, making it ideal for the design of circuits with limited board space.

The working principle of the fixed inductor involves the creation of a magnetic field when current flows through its wire coil. This magnetic field induces a back voltage, proportional to the rate of change of the applied current. This voltage is known as inductance, and it is what gives the inductor the ability to store energy in the form of a magnetic field. The inductance of an inductor is dependent on the number of turns in its wire coil, its permeability, the shape of the core, and the core material.

Applications for the LB2518T220MV range from power supply circuits to load balancing. It is commonly used in pulse and switch mode power supplies, where it acts as a line filter by reducing voltage and current spikes. The LB2518T220MV can also be used in filtering circuits to reduce noise and interference. It can also be used in AC/DC converter circuits, and audio amplifiers. Additionally, it can be used in antenna matching and line matching circuits for RF applications such as cellular phones and Bluetooth headsets.

In conclusion, the LB2518T220MV is a high-performance fixed inductor that is well suited for many applications. Its features include a low profile height, a maximum operating temperature of 105°C, and a saturation current of 1.2A. It is suitable for power supplies, filtering, load balancing, antenna matching, and audio amplification circuits. With its multitude of applications, the LB2518T220MV is an excellent choice for many challenging electronic design applications.
