BENEFITS OF USING CAPACITOR
ARRAYS
AVX capacitor arrays offer designers the opportunity to
lower placement costs, increase assembly line output
through lower component count per board and to reduce
real estate requirements.
For high volume users of cap arrays using the very latest
placement equipment capable of placing 10 components per
second, the increase in throughput can be very significant and
can have the overall effect of reducing the number of place-
ment machines required to mount components:
If 120 million 2-element arrays or 40 million 4-element arrays
were placed in a year, the requirement for placement
equipment would be reduced by one machine.
During a 20Hr operational day a machine places 720K
components. Over a working year of 167 days the machine
can place approximately 120 million. If 2-element arrays are
mounted instead of discrete components, then the number
of placements is reduced by a factor of two and in the
scenario where 120 million 2-element arrays are placed there
is a saving of one pick and place machine.
Smaller volume users can also benefit from replacing
discrete components with arrays. The total number of place-
ments is reduced thus creating spare capacity on placement
machines. This in turn generates the opportunity to increase
overall production output without further investment in new
equipment.
Reduced Costs
Placement costs are greatly reduced by effectively placing
one device instead of four or two. This results in increased
throughput and translates into savings on machine time.
Inventory levels are lowered and further savings are made
on solder materials, etc.
Space Saving
Space savings can be quite dramatic when compared to
the use of discrete chip capacitors. As an example, the
0508 4-element array offers a space reduction of >40% vs.
4 x 0402 discrete capacitors and of >70% vs. 4 x 0603
discrete capacitors. (This calculation is dependent on the
spacing of the discrete components.)
Increased Throughput
Assuming that there are 220 passive components placed in a
mobile phone:
A reduction in the passive count to 200 (by replacing
discrete components with arrays) results in an increase in
throughput of approximately 9%.
A reduction of 40 placements increases throughput by 18%.

GENERAL DESCRIPTION
AVX is the market leader in the development and manufacture of
capacitor arrays. The smallest array option available from AVX, the
0405 2-element device, has been an enormous success in the
Telecommunications market. The array family of products also
includes the 0612 4-element device as well as 0508 2-element and
4-element series, all of which have received widespread acceptance
in the marketplace.
AVX capacitor arrays are available in X5R, X7R and NP0 (C0G)
ceramic dielectrics to cover a broad range of capacitance values.
Voltage ratings from 6.3 Volts up to 100 Volts are offered. AVX
also now offers a range of automotive capacitor arrays qualified to
AEC-Q200 (see separate table).
Key markets for capacitor arrays are Mobile and Cordless Phones,
Digital Set Top Boxes, Computer Motherboards and Peripherals
as well as Automotive applications, RF Modems, Networking
Products, etc.
