Fixed inductors refer to all kinds of coil windings with a certain shape but no moving parts, whose inductance values are stable. L-05B39NJV6T is one of the many different types of fixed inductors. It is typically used in low frequency applications in the electronics and automation industries.

The L-05B39NJV6T is a small-size, lead-free device with a radial-wire lead configuration designed for high-density mounting. This type of fixed inductors is made up of an iron core, an outer casing and two winding wires. When the electrical field between the two ends of the winding wire is removed, static magnetic fields will form around the iron core. The current will generate a magnetic field, and the magnetic field will interact with the static magnetic fields to form a reciprocal inductance. Thus, the inductance between the two ends of the winding wire rises.

The core size of L-05B39NJV6T is 5 x 3.9mm, making it a small size device. The inductance of this type ranges from 1uH to 330uH and the core material consists mainly of ferrite and amorphous material. It also features a low DC resistance, usually less than 5mΩ, making it ideal for low frequency applications, such as filtering and coupling applications.

The working principle of L-05B39NJV6T is fairly simple. When current flows through the winding coils, the additional or static magnetic fields produce a strong inductive reactance, resulting in an increase in the inductance of the inductor. This increase is proportional to the number of turns of the winding coil, and when there is no current, the inductance is not affected.

L-05B39NJV6T is widely used in various industries, such as consumer electronics, automotive electronics, battery multi-protection, etc. In the automotive industry, it is mainly used to reduce the rush current of the power supply, improve noise immunity, and reduce the electromagnetic interference of the power system. In consumer electronics, it is mainly used for DC and audio filtering, power transformers, etc. In battery protection, it is mainly used in battery switch and standby protection circuit.

Overall, the L-05B39NJV6T is a very versatile fixed inductor, widely used in different applications due to its unique features and working principle. It is a relatively small size device with a radial lead configuration that facilitates high-density mounting. Moreover, its low DC resistance makes it suitable for low frequency applications, such as filtering and coupling applications. Thanks to its broad applications, it is a very popular device for various industries.
