The capacitors are based on a fusion of conductive polymer and electrolyte and are intended for use in a range of applications, from control circuits in automotive engine control units (ECUs), battery management systems (BMS) to motor drive circuits in electric pumps, radiator fans, and to advanced driver assistance systems (ADAS) applications (such as cameras, sensors, and control circuits).
Reducing board size is necessary for securing mounting space, which requires a reduction in the number and size of capacitors and large current, explains the company.
The company claims that the ZKU series of conductive polymer hybrid aluminium electrolytic capacitors has the industry's largest capacitance by using its electrode foil area expansion processing technology.
The capacitors have achieved 50% and above more capacitance than the existing ZC series capacitors and 20% or more than the ZK series.
Currents are 1.3 times as much as those of the conventional ZC series products and equivalent to those of the ZK series, reports the company.
The capacitors can be used for voltage stabilisation at ECU power supply input sections (input filter) and current stabilisation in motor drive circuits (DC-Link).
