Multilayer chip ceramic capacitors

Multilayer chip ceramic capacitor (MLCC) is referred to as chip capacitor for short. It is a capacitor formed by laminating and co firing multi-layer ceramic membranes with printed metal electrodes to form an integral monolith structure, and then coating a layer of metal on two ends by dip coating, sintering and electroplating

Leads Ceramic MLCC

Lead Ceramic MLCC is a kind of radial lead type ceramic capacitor, which is coated with resin coating after bonding two wires on the external electrode of MLCC through solder. Such capacitor not only has the special characteristics of MLCC, but also integrates the effects of reducing mechanical and thermal load of wires, insulation and humidity isolation brought by resin coating
