APPLICATION BASIC DESIGN
A high performance electrolytic capacitor
designed for automotive applications
with high vibrations and high ambient
temperatures.
An electrolytic capacitor with outstanding
electrical performance. It is polarized with
the negative pole connected to the case. The
outer case has a plastic cover.
The low ESR is a result of a low resistive
electrolyte/paper system. Together with the
TDC thermal concept, this range has very
high ripple current capability. The capa-
citor is suitable for both mobile and aircraft
applications, with operation up to 125°C.
