Application Guidelines
Sources of EMI
Electromagnetic interference occurs naturally from terres-
trial sources such as lightning discharges, precipitation,
and sand and dust storms, in addition to cosmic noise
emanating from sources within and outside our solar
system. Man-made sources include power lines, rotating
machinery, ignition systems, television and radio receivers,
fluorescent lights, power amplifiers, computing devices
and transmitters of all types.
Interference Suppression
Filter networks suppress electromagnetic interference
in two basic ways. The capacitor elements shunt the
interference to ground, and the series inductor elements
raise the impedance of the line making the shunt
capacitor elements even more effective.
Capacitor Elements
The types of capacitors used in Spectrum Control filters
are often referred to as feed-thru capacitors due to their
physical geometry.
inductance compared to standard leaded capacitors.
Also, this design effectively prevents radiation from the
input coupling directly with the output of the capacitor,
unlike leaded or chip capacitors. The combination of
low inductance and high input/output isolation provides
excellent shunting of EMI for frequencies up to and
beyond 1 GHz.
have buried electrodes and can be constructed as a single
capacitor or as two capacitors, as used in a Pi section
filter. This type of device can have capacitance values from
10 pF to 0.1 µF and typical working voltage ratings up to
2500 VDC. Due to the simple construction, these capaci-
tors are very efficient at frequencies up to 10 GHz and
exhibit no pronounced resonances.
very high capacitance parts in standard sizes or for smaller
filters where the required capacitance cannot be achieved
by a ceramic tube. This type of capacitor consists of alter-
nate layers of opposite polarity electrodes separated by a
ceramic dielectric. Typical capacitance values from 100 pF
to 10 µF are available with working voltages up to 400 VDC.
Inductive Elements
Ferrite sleeves are used with tubular capacitors since
they can be conveniently accommodated inside the tube
to provide a very compact filter. They are also used with
discoidal capacitors in some applications. Wound inductors
are used with discoidal capacitors to provide very high
performance filters.
