Inductors are electronic components which restricts current flow to create electric fields with the principle of either magnetic or electrostatic induction. In the field of electronics, they are mainly used to filter or store signals and energies with specific frequencies. Ultimately, they are used to convert the signals into useful energy. Among the various types of inductors, fixed inductors, also known as fixed coil inductors, are a specific type designed to provide inductance over a wide range of AC frequencies.

B82412A1102J is a type of fixed coil inductor. It is designed for use in automotive, industrial and general electronic applications. It has a high inductance rating of 1.9mH and a maximum permissible ambient temperature of 105°C. It also has a wide, continuous operating temperature range from -40°C to 105°C. The B82412A1102J is UL recognized according to the UL 1412 standard and is RoHS compliant.

In terms of its working principle, fixed coil inductors are based on the basic principle of inductive reactance. The flux density of the core and the number of turns in the coil determine the amount of inductance offered by the inductor. When there is an AC passing current through the conductor, the magnetic field created by the current will induce an electromotive force in the coil. This then creates a self-inductance of the coil, which opposes the AC current and restricts its flow.

In comparison to other inductors, fixed coil inductors can offer higher levels of inductance over a range of AC frequencies. As a result, they are widely used in a variety of applications. These applications include power supplies, resonators, and filters in telecommunications, automotive, industrial, and consumer electronics. In particular, they are commonly used for energy storage in DC-DC converters, and as EMI and RFI filters.

B82412A1102J is one of the many commonly used fixed coil inductors for both commercial and industrial use. This particular model has a wide operating temperature range, a high inductance rating, and has UL and RoHS certifications. Ultimately, it is suitable for use in automotive, industrial and general electronic applications requiring robust inductors.
