Naming method for surface mount capacitors 1

Single chip ceramic capacitors (commonly known as surface mount capacitors) are currently widely used components. As for the surface mount capacitors produced by AVX company, there are different specifications such as NPO, X7R, Z5U, Y5V, etc., and different specifications have different uses. Different companies may have different naming methods for capacitors with different performance mentioned above. Here, we refer to AVX's naming method. For products from other companies, please refer to their product manuals. Due to different filling media at the same volume  diode

Single chip ceramic capacitors (commonly known as surface mount capacitors) are commonly used components with high usage. As for the surface mount capacitors produced by AVX company, there are different specifications such as NPO, X7R, Z5U, Y5V, etc., and different specifications have different uses. Below, we will only introduce the performance and applications of commonly used NPO, X7R, Z5U, and Y5V, as well as the ordering items that should be noted in procurement to attract everyone's attention. Different companies may have different naming methods for capacitors with different performance mentioned above. The naming method we quoted here is from AVX company. For products from other companies, please refer to their product manuals. diode

The main difference between NPO, X7R, Z5U, and Y5V is their different filling media. Under the same volume, capacitors composed of different filling media have different capacities, resulting in different dielectric losses and capacity stability of the capacitors. So when using capacitors, different capacitors should be selected according to their different functions in the circuit. diode

An NPO capacitor

NPO is the most commonly used single-chip ceramic capacitor with temperature compensation characteristics. Its filling medium is composed of rubidium, samarium, and some other rare oxides.
