Inductors are passive electronic components that store energy in a magnetic field when electrical current flows through them. They play a crucial role in various electronic circuits, including power supplies, filters, and radio frequency (RF) applications. Accurate measurement of inductance is essential for ensuring optimal circuit performance and maintaining quality control in manufacturing processes. This article aims to provide an overview of popular inductor measurement products, their functionalities, and factors to consider when selecting the right tool for your needs.
Inductance is defined as the property of an inductor that opposes changes in current. It is measured in Henries (H), with common subunits being millihenries (mH) and microhenries (µH). Several factors influence inductance, including the core material, the geometry of the inductor, and the number of turns in the coil. Understanding these basics is vital for anyone involved in electronics, as the performance of circuits can be significantly affected by the inductance values of the components used.
Inductors are widely used in various applications:
1. **Power Supplies**: Inductors are essential in switching power supplies, where they help smooth out voltage and current fluctuations.
