Multilayer SMD ceramic capacitor are the SMD capacitor that we usually see. They are one of the components with a relatively large amount of electronic products. The most commonly used models are NPO, X7R, Z5U, Y5V and other different materials. The materials have different uses. Let me give you a brief introduction to the performance of these materials, NPO, X7R, Z5U and Y5V.
NPO SMD capacitor are one of the most stable capacitor in terms of capacitance and dielectric loss. This material has the most stable electrical properties and hardly changes with changes in temperature, voltage and time. It is suitable for low loss and high frequency with stability requirements. Circuit.
SMD capacitor made of X7R are the most stable in temperature of all materials. X7R SMD capacitor are mainly used in industrial applications. Its main advantage is that the chip capacitor capacity can be relatively large in the same volume.
SMD capacitor made of Z5U are called general-purpose multilayer SMD ceramic capacitor. Before choosing, we must first consider the operating temperature range. For the Z5U material chip capacitor, the main advantage is its small size and low cost.
Y5V material SMD capacitor is a kind of SMD capacitor with a certain temperature limit, and its capacitance can vary from +22% to -82% within the range of -30℃ to 85℃. The high dielectric constant of Y5V allows capacitor up to 4.7μF to be manufactured in a small physical size.
