Which is better, SMD inductor or plug-in inductor?

It can be seen from the external packaging mode that the SMT inductor has no pin; The plug-in inductor obviously has a very long pin; Although the plug-in inductance has obvious advantages in cost; But the power inductor of SMT can reduce the manual of plug-in; The maximum advantage patch power inductor has no pins; [...]

The basic knowledge of SMD inductor is analyzed in detail

Chip inductors, also known as power inductors, high current inductors and surface-mounted high power inductors. Features: miniaturization, high quality, high energy storage and low resistance. In general, the inductance of an electronic circuit is a hollow coil, or a coil with a magnetic core. And the power inductor also has the hollow coil, also has [...]

Why does SMT power burn?

I. failure reason of SMD inductive power: 1. The magnetic core will not release if the magnetic flux density is too high during the processing; 2. When there are impurities or hollow materials in the magnetic core, the magnetic permeability of the magnetic core will be deviated because the magnetic field of the magnetic core [...]

PCB pressing hole notes

Notes for pressing holes 1. The pressing hole can reduce the wave peak welding set by welding this kind of components. It is easy to change parts. 2. New drill bit drilling is generally adopted for pressing hole, because of the high requirement for its precision, our company's conventional pressing hole control tolerance is /-0.05mm, [...]

What is the difference between inductance _ common – mode inductance and differential – mode inductance

What is inductance Inductance, or inductance, is a property of a closed circuit that gives rise to an electromotive force to resist a change in the current passing through the closed circuit. This inductance, called self-inductance, is a property of the closed loop itself. If the current in one closed circuit changes and an electromotive [...]

Precautions for circuit board crimping holes

Notes on crimping holes 1. The crimping hole can reduce the wave soldering set for soldering such components once. It is very easy to replace parts. Of course, if you change it many times, it will affect the reliability of the hole. 2. The crimping hole is generally drilled with a new drill bit, because [...]
