New electrolytics poised to replace banks of costly wet tantalum capacitors
New Yorker Electronics
Recently introduced as the world’s only hermetic aluminium electrolytic
capacitor with a glass-to-metal seal, Cornell Dubilier's new MLSH Series is
now available through New Yorker Electronics.
With no dry-out mechanism and high capacitance retention at low
temperatures, the technology in the MLSH Series is poised to replace banks
of costly wet tantalum capacitors, says the company.
The new Slimpack, type MLSH, is 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,
this capacitor technology has extraordinarily long life in order to meet the
most demanding defence and aerospace applications.
Cornell Dubilier expects the 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 manufacturer, 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
if at -55C. High capacitance at low temperature is a key requirement for
power supplies in demanding operational environments.
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.
