Fixed inductors are one of the staples in all electrical and electronic systems. High quality inductors, such as the AX97-20681 model, are critically important components that enable reliable and efficient system operation. In this article we will look at the application field and working principle of these inductors.

Part 1: Application Field

Fixed inductors are used in a range of applications where a precise inductance value is needed, such as in AC-DC power supplies, DC-DC converters, low dropout regulators, multi-voltage systems, voltage follower circuits, RF amplifiers, and more. The AX97-20681 model in particular is an excellent option for use in high-reliability industries such as aerospace, military, and medical where customers require the highest levels of performance.

The AX97-20681 series has a rated voltage of up to 100VDC, an inductance range of 0.3 μH to 56 μH, and a rated current of up to 13A. Depending on the specific needs of the application, these inductors come in various package styles for grab-and-go convenience. All of the inductors in this series meet the requirements of lead-free RoHS regulations, adding to their appeal for many end-users.

Part 2: Working Principle

Inductors are composed of a coil of wire that is wrapped around a magnetic core, and they can be used to store or pass energy through electromagnetic induction. When electric current flows through the inductor a magnetic field is generated within it, which induces a voltage in the inductor’s windings due to current flow through the inductor. This voltage is proportional to the rate of change of current through an inductor, and this is referred to as the inductor’s inductance. The magnitude of the current, as well as the magnetic core material and size, determine the inductance value.

The AX97-20681 series offers exceptional performance due to a closed magnetic core design that effectively contains the flux within the inductor, improving the inductor’s output efficiency. The high-temperature resistant alloy core material also ensures a low loss factor and high inductance stability over time and temperature. The reliability and performance of this inductor make it the perfect choice for any application that requires a high-quality, high-performance fixed-inductor solution.

In conclusion, fixed inductors such as the AX97-20681 series are indispensable components in electrical and electronic systems. They are used in a broad range of applications and offer excellent efficiency, reliability, and performance. The AX97-20681 series in particular is ideal for demanding industries, offering lead-free RoHS compliance, a range of package styles, and excellent inductance stability.
