Fixed Inductors

Inductors are electrical components that store energy in the form of magnetic fields. Fixed inductors, which are also known as air core inductors, magnetic core inductors, or inductors, are coils that are used to create a circuit element with a fixed inductance. The inductance of a fixed inductor is related to its physical dimensions, such as the number of turns, the length and thickness of wire, and the composition of the core material. Commonly used inductor materials include ferrite, iron powder, carbon powder, and ceramic.

The PA4548.472NLT is a fixed inductor from Vishay manufacturers. This inductor offers a robust, cost-effective solution for general-purpose applications. It operates in a wide frequency range, from 10kHz to 1GHz, and features a high inductance of 4.7μH, making it ideal for power line conditioning, voltage-supply filtering, and industrial/automotive applications.

This fixed inductor features a Q factor of 60, a self-resonant frequency of 350MHz, and a total height of 6.2mm. The core material of this inductor is a mix of iron and magnetic powder, which makes it suitable for high-frequency, high-power applications. The PA4548.472NLT has an electrical resistance of 0.25ohm, making it an efficient conductor of electric current.

To improve thermal management, this inductor features a tin-plated copper core wire. The coil is cased with a plastic sleeve that provides further protection from corrosion. This sleeve also helps to secure the inductor in place and ensures that it won’t move during operation. To increase durability, the PA4548.472NLT’s coil is encapsulated in an epoxy resin that offers great insulation properties.

In terms of its operational principle, fixed inductors consist of a coil of conductive wire wrapped around a core. When current passes through the coil, it induces a magnetic field around the core, which stores energy in the form of a magnetic field. This interaction between the magnetic field and the coil results in an inductance that opposes changes in the electric current passing through the circuit. This inductance can be used to filter or condition the power supply, increasing signal strength, and reducing noise.

The PA4548.472NLT fixed inductor is an ideal choice for applications that require a cost-effective solution with great performance. Its high Q factor, inductance value, and low electrical resistance make it suitable for power line conditioning, voltage-supply filtering, and various industrial and automotive uses.
