Fixed Inductors

Fixed inductors are electrical components used in a variety of applications, ranging from power supplies to high-end audio. Communications systems and radio apparatus rely heavily on inductors for filtering, impedance tuning, voltage regulation, and noise reduction.

Inductors are broadly classified into three categories, based on their size and the manner in which they store energy: air core inductors, ferrite core inductors, and ferromagnetic core inductors. Air core inductors are the least bulky of the three and function as a simple coil of wire. Based on the complexity of the coil design, an air core inductor can be designed to offer various frequencies, bandwidths and inductance values. Since there is no magnetic core, an air core inductor has the advantage of not producing additional noise, although the Q factor is typically low.

Ferrite core and ferromagnetic core inductors use a magnetically permeable material (such as iron or ferrite) as a core, which increases the inductance of the coil. Both ferrite core and ferromagnetic core inductors have a higher Q factor and higher efficiency than air core inductors. The trade-off is these materials may introduce some unwanted thermal noise, due to the magnetic core.

2256-32K Application Field and Working Principle

The Fixed Inductor 2256-32K is a rugged, cost-effective solution with an impressive inductance value of 32 kΩ. The component features a ceramic-core, double-wire wound construction with non-polarized connections. This construction reduces frequencies, allowing for better efficiency, noise and temperature stability, and an enhanced electrical performance compared to air-core form factors.

The Fixed Inductor 2256-32K is suitable for RF systems, wireless communication systems and cellular phone applications. The high frequency characteristics inherent to air-core inductors are also applicable to this device, making it ideal for RF resonators, oscillators, and filters. This inductor also has built-in creepage protection that provides insulation against electric current flowing through or along the surface of the device.

The Fixed Inductor 2256-32K uses the principle of self-induction to store electrical energy in the form of a magnetic field. When current passes through the coil, the magnetic field is generated in the winding which stores the energy. This action is what is known as self-induction, and is at the heart of how the device works.

The device also features a low profile form factor, which allows for a smaller footprint and higher component density. The terminal pins are molded to the top of the device, giving it enhanced physical stability. This component offers high thermal performance, making it easier to dissipate generated heat.
