What are the materials of chip capacitors?

Full name of chip capacitor: multilayer (laminated, laminated) chip ceramic capacitor, also known as chip capacitor, chip capacitor. English abbreviation: MLCC.

NPO, X7R, z5u and Y5V are commonly used.

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

X7R capacitor is called temperature stable ceramic capacitor.

Z5u capacitor is called "universal" ceramic monolithic capacitor.

Y5V capacitor is a general capacitor with certain temperature limit. Its capacity can vary from 22% to - 82% in the range of - 30 ℃ to 85 ℃.
