Monolithic capacitors are another name for multilayer ceramic capacitors. The English name monolithic ceramic capacitor or multi-layer ceramic capacitor, referred to as MLCC, is widely used in electronic precision instruments. Various small electronic devices are used for resonance, coupling, filtering, and bypass. Monolithic capacitors are larger than ordinary ceramic capacitors (10pF~10μF), and have the advantages of large capacitance, small size, high reliability, stable capacitance, high temperature resistance, good insulation, and low cost, so they are widely used. Monolithic capacitors can not only replace mica capacitors and paper capacitors, but also replace certain tantalum capacitors, and are widely used in small and ultra-small electronic devices (such as liquid crystal watches and micro instruments).With the improvement of the reliability and integration of chip-capacity products, the scope of their use becomes wider and wider, and they are widely used in various military and civilian electronic complete machines and electronic equipment. Such as computers, telephones, program-controlled switches, sophisticated testing instruments, radar communications, etc.
