Multilayer Ceramic Capacitors(Stack type)
They have high capacitance by parallel connecting high voltage multilayer ceramic capacitors with multiple metal frame. They have smaller ESR and ESL compared to aluminum electrolysis capacitors or film capacitors. In some frequencies, it will help reducing size and noise of equipments with high ripple smoothing characters at small capacitance.
Series Line Up
