Automotive capacitors provide long lifetime at high temperature

The new ZUU series of conductive polymer hybrid aluminum electrolytic capacitors from Panasonic Industry offer highly attractive specifications for automotive applications operating in demanding conditions. 

The AEC-Q200-qualified ZUU series features high maximum ripple-current handling capability of 6.1 Arms, a 60% increase over the previous best Panasonic offering in its ZS series, at 125°C and 135°C. Capacitance values up to 1,000 μF mark an 80% increase over the Panasonic ZU series offering, while ESR is just 8 mΩ. The ZUU also provides high reliability, with endurance rated at 4,000 hours at both 125°C and 135°C.

These technical improvements make the surface-mount ZUU series polymer hybrid capacitors ideal for use in under-the-hood automotive applications such as pumps, electric power steering, cooling fans, high-current dc-dc converters, and advanced driver assistance systems. More widely, the ZUU capacitors are suitable for the inverter power supply in industrial applications, and on the dc side of both inverter and rectifier circuits in general power supplies.
