Hello! Electrolytic capacitor package size is usually considered clearly at the time of design, some people like to design with reference to the existing conventional models, some people want to design according to their own needs, these requirements are reasonable, some devices use small volume design aluminum electrolytic capacitors in order to reduce the volume.
CECTNs 200V1200uF bullhorn aluminum electrolytic capacitors are available in 35*35mm and 35*40mm sizes, which can meet most customers needs.
