Single-ended
Aluminum electrolytic capacitors
Introduction
Aluminum electrolytic capacitors
from EPCOS are constantly being
enhanced to specifications meeting
the typical requirements in the auto-
motive industry. This section presents
the latest innovations within the single-
ended product line. All existing series
have been improved and new series
introduced. In addition, special lead
configurations have been added to
provide a broad range of lead
options. The Protection Against
Polarity Reversal (PAPR) concept has
been extended with J leads and bent
90° leads. Blister packaging is now
introduced as standard for all PAPR
configurations. This results in better
quality and convenience for the cus-
tomer.
The new B41853 series was devel-
oped to achieve excellent perform-
ance in airbag applications, covering
a wide range of capacitance values
up to 6800 µF.
The high-reliability series B41868 for
high temperatures up to 150 °C and
the new B41896 series with long use-
ful life for temperatures up to 125 °C
take full advantage of higher ripple
current capability in compact can
sizes, ensuring exceptional perform-
ance in powertrain applications and
control units installed in the vicinity of
the engine.
The B41888 series has also been up-
graded and provides very long useful
life and high ripple current capability
at 105 °C.
The B43866 series combines high
temperature resistance up to 125 °C,
at high operating voltages up to 350 V,
and is a potential solution for new
applications such as piezo injector
technology.
EPCOS quality is certified by the
international standards ISO 9001 and
ISO/TS 16949. In addition, the intro-
duction of new mechanical and
technical features makes EPCOS
single-ended aluminum electrolytic
capacitors one of the best and most
competitive products worldwide.

Shelf life of the capacitor up to 15 years at storage temperatures up to 40 °C. To ensure solderability,
the capacitors should be built into the application within one year of delivery. After a total of two years’
storage, the operating voltage must be applied for one hour to ensure the specified leakage current.
