GENERAL DESCRIPTION
W2F/W2H
Series
0805
W3F Series
Availableinbothastandard0805and1206size, AVX’slineoffeedthru
capacitors are ideal choices for EMI suppression, broadband I/O
filtering, or Vcc power line conditioning. The unique construction
of a feedthru capacitor provides low parallel inductance and offers
excellent decoupling capability for all high di/dt environments and
provides significant noise reduction in digital circuits to <5 GHz. A
large range of capacitor values are available in either NP0 or X7R
ceramic dielectrics. AVX FeedThru filters are AEC Q200 qualified.
High reliability screening options, and SnPb termination are
available for spacecraft designs.

internal electrode design.
ABSTRACT
Today's high speed, miniaturized semiconductors have made EMI
issues a key design consideration. This paper briefly defines EMI and
illustrates the capability of SMT feedthru capacitors.
An application comparison between an SMT feedthru and a discrete
capacitor is shown in Figure 1.
WHAT IS EMI?
The term EMI stands for Electromagnetic Interference and refers to
signals/energy interfering with a circuit or systems functions.

In an electronic system, two classes of energy are generated -
wanted and unwanted. Both are potential sources of EMIT Wanted
signals such as clocks and bus lines could cause EMI if they were
not decoupled, terminated or filtered properly. Unwanted signals (cell
phones, police radios, power supply noise, etc.) could be conducted
or radiated into the circuit due to poor circuit layout, improper
decoupling or a lack of high frequency filtering.

The key difference between the two filtering methods is that the
feedthru has a much lower inductance between the signal line and
ground than the capacitor. The difference in inductances can be in
the range of roughly one order magnitude with a feedthru capacitor.
This inductance can be shown in an electrical sense through the
model for a feedthru and a capacitor (Figure 2).
In either type of EMI signal interference, the system could be
rendered useless or put into a state which would cause early failure
of its semiconductors. Even worse, the unwanted energy could cause
an incorrect answer to be generated from a computer by randomly
powering a gate up or down. From all of this we can gather that EMI
is a complex problem, usually with no one solution. EMI interference
can be a random single shot noise (like a SCR firing) or repetitive
in nature (stepper motor or relay noise). The interference can enter
into our designs either by being induced by E/B fields, or it can be
conducted through control lines or a communication bus. EMI can
even be self generated by internal components that generate steep
risetime waveforms of voltage or current.

HOW CAN EMI BE CONTROLLED?
FEEDTHRU FILTER
SMT CAPACITOR
EMI is most efficiently controlled by realizing it to be a design
parameter in the earliest stages of the design. This way, the board
layout can be optimized with large power and ground planes which
will be low impedance in nature. The use of SMT feedthru filters will
yield optimal results.

to Discrete Capacitors
The feedthru capacitor has a minimized parallel inductance and an
optimal series inductance (which broadens the frequency response
curve). Typical attenuation graphs are shown in Figure 3A.
SMT FEEDTHRU CAPACITORS
AVX introduced feedthru capacitors to supply a broadband EMI filter
capacitor for source suppression and receiver noise reduction.
These curves demonstrate feedthru capacitors advantage of a
broad frequency response with high attenuation. They also serve as
a comparison to the inductance of even lower inductance devices
(primarily used in extreme decoupling cases and switch mode
power supplies) - see Figure 3B.
SMT feedthru capacitors use the same material systems as
standard ceramic capacitors. They exhibit the same reliability and
can be processed in the same end user production methods as
standard capacitors. What feedthru capacitors offer is an optimized

AVX's feedthru capacitors have additional technical terminologies
relative to standard ceramic capacitors. The reason for this is due
to the series manner in which the feedthru element is connected to
the circuit.

The most important term is DC Resistance. The DC resistance of
the feedthru is specified since it causes a minor signal attenuation
which designers can calculate by knowing the maximum resistance
of the part.
The maximum current capability of the part is also of interest
to designers since the feedthru may be placed in series with the
voltage line.

APPLICATION AND SELECTION OF SMT
FEEDTHRU CAPACITOR FILTERS
EMI suppression and receiver noise reduction can be achieved
most effectively with efficient filtering methods. Attenuations of
over 100 dB are achievable depending on the complexity and size
of the filters involved.

However, before filtering is discussed, another EMI reduction
method is noise limiting, using a series element (inductors or
resistors). This method is easy to implement and inexpensive. The
problem it poses is that it can only reduce noise by -3 to -10 dB.
Because of that, series element EMI reduction is primarily used
where there is a poor ground.

SMT feedthru filter capacitors can actually replace discrete L/C filter
networks (depending on the frequency response needed). The SMT
filter capacitors should first be chosen for its specific frequency
response. Then the voltage rating, DCR, and current capability must
be evaluated for circuit suitability. If there is not a match on voltage,
current and DC resistance ratings, the designer must select the
closest available frequency response available on parts that will
meet the design's power spec.
