2023-01-03

One of the most common forms of magnetic components is inductance, which has a certain inductance value and therefore its impedance increases with the increase of frequency. This alone can be considered as a first-order high-frequency filter; When the filtering object we are discussing changes from a single current path (loop or circuit loop) to tw...

How to Select the Right Inductor for Switching Power Supplies

Date：

2022-07-23

An inductor is a common energy-storing passive component in circuits, playing roles such as filtering, boosting, and bucking in the design of switching power supplies. In the early stage of scheme design, engineers not only need to select appropriate inductance values, but also consider the current that the inductor can withstand, the DCR of the co...

A Brief Analysis of Inductor Noise and Solutions

Date：

2022-06-02

1、The principle of noise generationNoise is generated by the vibration of objects. Let's take a speaker as an example to understand the principle of vibration.A speaker does not directly convert electrical energy into sound energy. Instead, it uses a carrier current (voice coil or coil) to interact between magnets, making the voice coil vibrate and...
