The multilayer planar array is an application specific multi
capacitor array designed for use in multiway EMI filter
circuits. Derived from discoidal capacitor theory, it provides
capacitance between the outside perimeter and the internal
through holes.
The most common use of planar arrays is as the capacitor
element in filter connectors, although they are also suitable in
many other applications.
Syfer’s core wet manufacturing process and ceramic handling
expertise allows components to be produced with mechanical
precision and electrical accuracy, enabling a filter assembly to
withstand the most rigorous of electrical specifications. This
has resulted in Syfer’s position as the manufacturer of choice
for the filter connector industry. To date, Syfer have delivered
in excess of 3,000 different designs of planar array.
The quality and reliability of Syfer’s planar arrays has been
uniquely recognised by the approval of NASA for their use in
the International Space Station.
Mechanical
With many years experience, Syfer have developed a
comprehensive range of designs, including planform designs
for the following connectors:
Special custom shapes and layouts can also be
accommodated. Complex shapes including internal and
external radii, multiple hole diameters and alignment guides
can be considered.
As a guide, Syfer can manufacture planars to a maximum of
3.18mm (0.125”) thick and to a maximum of 100mm (4.0”)
diameter or square.
Standard termination finish is gold plate over nickel for
maximum electrical and mechanical performance. Options
include conventional silver-palladium (AgPd) or silver-platinum
(AgPt) fired terminations.
Solderless assembly/compliant spring clip
Solderless assembly of planars can be accommodated by the
inclusion of compliant spring clips into the holes, allowing the
array to be push fitted to through contact pins.
Syfer can supply a standard range of solder-in spring clips,
or fit customer supplied compliant clips before shipping the
finished array assembly.
Contract assembly and technical back-up
Having an EMI filter assembly line alongside the ceramic
manufacturing area allows Syfer to offer unprecedented
technical back-up and advice to planar array and discoidal
customers. This can include design and handling advice and
forensic analysis assistance. Syfer personnel have many
years experience in the use of planar arrays, having been
involved directly in the development of the technology from its
inception.
Syfer are also able to offer sub contract and prototype
manufacturing services to planar customers and connector
companies.
