 203/5000 Monolithic ceramic capacitors (commonly known as patch capacitors) are commonly used components with a relatively large amount at present. In terms of patch capacitors produced by AVX company, there are different specifications such as NPO, X7R, Z5U and Y5V, which have different USES. Below, we only introduce the commonly used NPO, X7R, Z5U and Y5V, their performance and application, as well as the matters that should be paid attention to in procurement to attract your attention. Different companies may have different naming methods for capacitors with different performances mentioned above. Here we refer to the naming method of AVX company. For products of other companies, please refer to the product manual of this company

           (6)In many circuit diagrams abroad, it is often seen that the capacitor of "OS -- CON" trademark is the organic semiconductor aluminum solid electrolytic capacitor produced by SANYO company in Japan. Its biggest characteristic is that although it is an electrolytic capacitor, it has the same high frequency characteristics as a film capacitor. Secondly, the equivalent series resistance is small and insensitive to temperature. The third is through the larger ripple current. For example, when using 30uH and 1500uF/10v aluminum electrolytic capacitor to form LC filter, if using os-con electrolytic capacitor (L unchanged), as long as 22uF/20V capacitor can achieve the effect
