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.

EMI REDUCTION THROUGH THE USE OF SMT FEEDTHRU CAPACITORS  
frequency response across a wide RF spectrum due to a modified  
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.

SMT CAPACITOR  
Figure 1. Comparison of Feedthru Capacitors  
to Discrete Capacitors  
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.  
Figure 2. Comparison of Feedthru Capacitors  
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.

1. Digital to RF interface filtering.  
2. Control line high frequency decoupling.  
3. Data and clock high frequency decoupling.  
4. Power line high frequency decoupling.  
5. High gain and RF amplifier filtering.
