Only hermetic aluminium electrolytic capacitor features glass-to-metal seal

22-06-2016 | Cornell Dubilier | Passives

Cornell Dubilier Electronics (CDE) has introduced the Slimpack, type MLSH,
the first in a series of hermetically-sealed aluminium electrolytic
capacitors that the company plans to introduce over the next several months.
With its glass-to-metal seal that prevents dry-out, the capacitor technology
has extraordinarily long life to meet the most demanding applications for
defence and aerospace applications, says the company.

The hermetic Slimpack is a spin-off of the company's established hermetic
Flatpack series. The company expects this technology to replace parallel
and series banks of wet tantalum capacitors for new and existing designs,
especially where bulk storage is paramount. According to the company, the
MLSH Slimpack measuring 1 x 1.5 x 0.5 inches will weigh less and will have
more capacitance than a parallel bank of three or more wet tantalum
capacitors as at -55C. High capacitance at low temperature is a key
requirement for power supplies used in high-performance and highly-demanding
applications.

In addition to its performance advantages at low temperature, the technology
is expected to have a significantly lower cost than a comparable bank of wet
tantalum capacitors, says the company.
