SMD capacitors Full name: multilayer (multilayer, laminated) chip ceramic capacitors, also known as chip capacitors, chip capacitance. English abbreviation: MLCC.

Four commonly used materials are NPO, X7R, Z5U and Y5V.

The NPO filling medium is made of rubidium, samarium and some other rare oxides.

X7R capacitors are called temperature-stable ceramic capacitors.

Z5U capacitors are called "universal" ceramic monolithic capacitors.

The Y5V capacitor is a general-purpose capacitor with a certain temperature limit, and its capacitance can vary from 22% to -82% in the range of -30°C to 85°C.
