Panasonic Corporation has announced that it has commercialised an anti-vibration, surface-mounted conductive-polymer hybrid aluminium electrolytic capacitor suitable for use in power circuits for automotive electric control units (ECUs) employed in hybrid electric vehicles, electric vehicles, and gasoline-powered vehicles. The company will launch the capacitor in January 2018.
With the growing demand for eco-friendly cars, energy efficiency and the need to comply with environmental regulation, more ECUs are being employed in cars. Mechanical and electrical in-vehicle components are also becoming integrated. This trend has created a need for more compact ECUs combined with better resistance to vibration. The capacitors employed to stabilise the voltage of a power circuit for the ECU and eliminate electronic noise are therefore increasingly required to be smaller in size and to show better anti-vibration performance. The company launches the industry's first surface-mounted conductive polymer hybrid aluminium electrolytic capacitor which is only 6.3 mm in diameter and achieves resistivity of 30G high vibration acceleration.

Panasonic's new conductive-polymer hybrid aluminium electrolytic capacitor have the following features:
- The capacitor is 6.3mm in diameter and is highly vibration acceleration resistant, contributing to smaller and more vibration-resistant ECUs.
- Size: 6.3mm in diameter, and 6.1mm or 8.0mm in height
- The newly developed capacitor withstands the vibration acceleration of 30G The conventional capacitor withstands vibration acceleration is 10G to the same aluminium electrolytic capacitor.
The capacitor renders unnecessary the anti-vibration techniques that are conventionally part of the board mounting process, thus allowing customers to streamline their production processes.
It reduces the use of bonding-based reinforcing measures, such as attachment using adhesives.
The capacitor benefits from Panasonic's unique auxiliary terminal structure, which offers highly reliable soldering properties.
