Capacitor Array
Multi-Value Capacitor Array (IPC)
GENERAL DESCRIPTION
A recent addition to the array product range is the Multi-
Value Capacitor Array. These devices combine two different
capacitance values in standard ‘Cap Array’ packages and
are available with a maximum ratio between the two capaci-
tance values of 100:1. The multi-value array is currently
available in the 0405 and 0508 2-element styles and also in
the 0612 4-element style.
Whereas to date AVX capacitor arrays have been suited to
applications where multiple capacitors of the same value are
used, the multi-value array introduces a new flexibility to the
range. The multi-value array can replace discrete capacitors
of different values and can be used for broadband decou-
pling applications. The 0508 x 2 element multi-value array
would be particularly recommended in this application.
Another application is filtering the 900/1800 or 1900MHz
noise in mobile phones. The 0405 2-element, low capaci-
tance value NP0, (C0G) device would be suited to this
application, in view of the space saving requirements of
mobile phone manufacturers.
ADVANTAGES OF THE MULTI-VALUE
CAPACITOR ARRAYS
Enhanced Performance Due to Reduced Parasitic
Inductance
When connected in parallel, not only do discrete capacitors
of different values give the desired self-resonance, but an
additional unwanted parallel resonance also results. This
parallel resonance is induced between each capacitor's
self-resonant frequencies and produces a peak in imped-
ance response. For decoupling and bypassing applications
this peak will result in a frequency band of reduced decou-
pling and in filtering applications reduced attenuation.
The multi-value capacitor array, combining capacitors in one
unit, virtually eliminates the problematic parallel resonance,
by minimizing parasitic inductance between the capacitors,
thus enhancing the broadband decoupling/filtering perfor-
mance of the part.
Reduced ESR
An advantage of connecting two capacitors in parallel is a
significant reduction in ESR. However, as stated above,
using discrete components brings with it the unwanted side
effect of parallel resonance. The multi-value cap array is
an excellent alternative as not only does it perform the
same function as parallel capacitors but also it reduces the
uncertainty of the frequency response.

• Max. ratio between the two cap values is 1:100.
• The voltage of the higher capacitance value dictates
the voltage of the multi-value part.
• Only combinations of values within a specific dielectric
range are possible.
