: Difference between "Average Value" and "RMS Value"
2023/6/26
This article will explain the differences between "Average Value" and "RMS Value". Difference between "Average Value" and "RMS Value" First, let's briefly explain the difference between "Average Value" and "RMS Value" (we will explain each in detail later). Taking the sine wave \(v=V_M\sin{{\omega}t}\) as an example: Average Value The average value is what you get when you replace "negative" values with "positive" ones and take the average. In other words, the average value, \(V_{AVE}\), is the average of the absolute value \(|v|\) of the sine wave \(v\). For example, in the case of the above figure, the average value \(V_{AVE}\) ...

: Types of IC Packages
2023/3/26
There are way too many different types of semiconductor (IC or transistor) packages. For example, SOP, QFN and BGA are some of the package names, but it is very difficult to understand which package represents which shape. Therefore, in this article, we have summarized the types and characteristics of each package in an easy-to-understand manner using diagrams. We hope you will find it helpful. List of IC Package Types The figure above shows the classification of packages. Packages can be broadly classified according to the following aspects. Difference in mounting method Whether the mounting method is "insertion mounting" or "surface ...
