Aluminum electrolytic capacitors
Introduction
The B41605 and B41607 series were
designed for applications with strin-
gent demands for power and current
carrying capacity at ambient temper-
atures ranging up to 150 C. Tinned
copper leads of 1.2 mm diameter, al-
so allowing determination of the poles
because of the different lead length,
can be either welded or soldered.
To stand up the specified vibrational
stability in an automobile, EPCOS
developed a special process for these
models, in the meantime patented,
that fixes the capacitor winding so re-
liably by a sophisticated corrugation
configuration that vibrational stability
up to 40 g can be specified even for
these large-sized models.

Specifications and characteristics in brief
Features
s
High reliability and long useful life, up to 2000 h at 140 C
s
Very high ripple current capability optimized for high frequencies
s
Compact design
s
Vibration resistance up to 40 g
s
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.
s
Variable pin configurations
Up to 40 g vibration stability version with wired terminals.
Weldable and solderable terminals. Tinned copper leads (
1.2 mm).
Snap-in with 3 terminals, protection against polarity reversal.
