Fixed Inductors

Fixed inductors, also known as chokes, are electrical components designed for storing energy in the form of a magnetic field. The AL12A12N5GTR is a particular type of fixed inductors that can be used for a variety of applications and performs differently depending on the surrounding environment and application.

Physical Design

The AL12A12N5GTR is a three-terminal, 12 ohm fixed inductor with a maximum working current of 5 amps. It is designed to handle a wide range of frequencies up to 10MHz and is protected against temperature changes of up to +150°C. The AL12A12N5GTR is made from a non-magnetic core material with a thick layer of isolation material to help prevent any electrons from leaking out and causing interference. The package dimension is 12.7mm x 12.7mm x 9.7mm.

Application Field

Fixed inductors such as the AL12A12N5GTR are usually used in switching power supplies, DC-DC converters, and voltage regulators. They are also used for filtering, power line noise reduction, and signal interference reduction in radio-frequency applications. The AL12A12N5GTR offers a wide range of applications due to its tightly controlled current limit, and allows for higher-power applications, including automotive electronics, LED lighting, telecom cooling, and more.

Working Principle

Fixed inductors, such as the AL12A12N5GTR, work on the principle of electromagnetic induction. When a current passes through the inductor, it creates a magnetic field which generates an opposing voltage, called the back electromotive force (BEMF). This BEMF creates a Faraday cage, which acts as a barrier to keep the electrons from leaking out and causing interference. The AL12A12N5GTR also works on a thermally-controlled principle, with a heatsink to dissipate excess heat.

The AL12A12N5GTR fixed inductor is a versatile component that is designed to provide steady power with minimum dissipated heat. Thanks to its tight current limit, it provides increased power efficiency and can be used in a variety of applications. The inductor is also designed with a wide temperature range, which ensures reliable operation in conditions from -40°C to +150°C.
