Introduction
Fixed Inductors are one of the most commonly used electronic components and are essential in a wide range of applications such as alternating current filtration, power supplies, low- and high-frequency oscillation circuits. They’re an important part of modern electronics, often discrete components, in which HCMA1305-R82-R is an advanced fixed inductor featuring low DCR and superior inductance stability.
Working Principle
Based on the concept of electromagnetic induction, an electric current will cause a magnetic field. The magnetic field will then induce an electric field. Thus, an oscillating electric field will create an oscillating magnetic field, which in turn will induce an oscillating electric field. This is known as the principle of electromagnetic induction or Faraday’s law. In fixed inductors, this process takes place continuously and requires no further energy.
Fixed inductors are constructed by winding coil conductors around a magnetic core, which intensifies and focuses the magnetic field for improved performance. The HCMA1305-R82-R fixed inductor uses exotic resonance technology to provide superior inductance stability while keeping the size and cost minimal.
