How to judgeHow good or bad is the quality of chip capacitors ?
How should we look at the quality of chip capacitors? In fact, the quality of chip capacitors can be checked from many aspects below, such as appearance and color. Next, the editor will take us to understand.
For example, let’s look at the appearance first
If it is a quality chip capacitor, then the appearance dimensions should be consistent with the dimensions marked on the surface or the dimensions marked on the manual or on the outer packaging. But if you get a chip capacitor on hand, I found this There seems to be some changes in the appearance size, for example, there are slight flaws or slight cracks, then there may be some problems with the size of the appearance, which may indirectly indicate that there are some problems with the capacitor. Secondly, look at the tin feet. If there are black spots, defects, cracks on the tin feet, and the upper and lower proportions of the tin feet Inconsistency and other defects indicate that the quality can be roughly judged by looking at it with the naked eye.
Here are other ways to judge the quality of chip capacitors:
What is the state of the chip capacitor? You can also look at the color. If it is a normal capacitor shipped from the factory, the appearance color will be uniform. There will be no color differences such as blackness and grayness in the same batch. But if When you get a chip capacitor, you will notice with your naked eyes The color of the surface has turned black, or even smoky, which may indicate that there is some problem with the capacitor, and this capacitor cannot be installed during installation and should be tested. If the test fails, it means there is a problem with the capacitor.
Another way to judge the quality of this chip capacitor is to use a digital bridge to detect it.
This is the most common method of identification. In fact, the detection process is also very simple, that is, directly adjust the bridge to the corresponding gear, and then use the bridge clamp to short-circuit all the two solder pins of the capacitor. Then observe the reading at this time. If the reading after stabilization is consistent with the capacitance value read in the capacitor's manual, or the deviation is very small and within the normal error range, it means that there should be no problem with the capacitor. of.
The editor will introduce here to you how to judge the quality of chip capacitors. Everyone should look for regular manufacturers when buying this kind of capacitors, because regular manufacturers will inspect each product when producing this product to ensure that these capacitors are of qualified quality, and these products produced by regular manufacturers have been inspected. With good outer packaging treatment, it can be well protected during transportation and will not be damaged due to transportation bumps. Regular manufacturers are responsible for the quality of the capacitors they sell. If users have quality problems with these capacitors, regular manufacturers can support exchanges. If you want to find regular manufacturers and companies, it is better to come to Shenzhen Special Power Technology Co., Ltd., Shenzhen Zhuandian Technology Co., Ltd. specializes in the agency and distribution business of chip capacitors, solid capacitors , chip electrolytic capacitors , resistors, tantalum capacitors , inductors, magnetic beads and other electronic components. The company has won the recognition and favor of our customers through thoughtful pre-sales and after-sales services!
