Axial-lead and soldering star
Aluminum electrolytic capacitors
Introduction
Axial-lead (B4169x/B43693) and sol-
dering star (B4179x/B43793) capaci-
tors can withstand temperatures up
to 150 °C and vibrations up to 20
g.
They are specified for an extended
useful life, offer outstanding electrical
performance at high reliability and
can withstand temperature changes
specified according to the typical
automotive requirements.
The innovative “automotive grade se-
ries” combines high ripple current
load and very low ESR with a com-
pact design.
The winding element is fixed by the
corrugation in the middle of the can.
Tensile strain applied to the tabs by
vibration stress is eliminated by cor-
rugated tabs. The lead wire (Ø 1 mm)
withstands high mechanical stress.
Moreover, low ESR and an extended
useful life contribute to their high reli-
ability and performance. These new
series from EPCOS have been up-
graded to operating temperatures of
150 °C and are designed for typical
automotive customers’ specifications.
Soldering star aluminum electrolytic
capacitors (with a star connector
terminal) have a comparable internal
winding construction to the axial-lead
types. The center contact acts as the
positive pole and the capacitor case
as the negative pole. The star con-
nector terminal is welded to the case
and so also has negative polarity. A
simple mounting method (pick and
place) is an added advantage of this
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.

The PC board hole arrangement
specified above is based on
circular arcs.
If, however, the mounting holes
have to be matched to a stan-
dard drilling raster, a spacing of
1.27 mm (1/20˝ ) has proved to
be sufficiently accurate if the
following arrangements are used:
