In recent years, ECUs mounted on vehicles have proliferated, and their power consumption has increased in step with vehicle electrification and the rise of autonomous driving. In particular, applications such as advanced driver assistance systems (ADAS), electric power steering (EPS), and automatic braking require a redundant design with two identical circuits installed in a vehicle to improve safety, resulting in a trend towards a further increase in the number of capacitors used per ECU. However, the limited space available for installation in the vehicle body requires ECUs to process high currents in a compact size, which increases the amount of heat generated within the ECU. Therefore, capacitors are required to not only be more heat-resistant but also smaller in form factor while offering more capacitance than ever before.Recently, the company has further evolved its proprietary electrolyte and high-precision electrode foil winding technology with a view to commercial production of the ZL series capacitors.
Features
- Through Panasonic Industry’s new proprietary electrolyte technology, the company has achieved high-capacitance type capacitors*2 guaranteed to operate at 135°C, an industry first *1.
- The ZL series capacitors come in five major sizes for automotive applications and have achieved the industry's highest level*2 capacitance.
- Saves space for capacitor mounting areas, contributing to a reduction in environmental impact through the miniaturization of ECUs and a decrease in the amount of parts and materials used.
*2 As of February 28, 2024, the industry's highest capacitance models in five major sizes (ø5 x 5.8 to ø10 x 10.2) for automotive applications included in the conductive polymer hybrid aluminum capacitors (Panasonic Industry data)
