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 innova
tions 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.
Different lead configurations available. For more details see pages 63–66.

Specifications and characteristics in brief
Features
Wide temperature range up to 150 °C
High reliability
Long useful life
High ripple current capability
Compact design
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.
