INSERTION LOSS
The insertion loss values specified throughout
this catalog are based upon an industry standard
of full load and balanced 50 ohm system in
accordance with MIL-STD-220A (at +25°C). The
actual attenuation performance in other circuits
will vary significantly with different values of
source and load impedance.
The insertion loss values in this catalog may
appear to be significantly lower than that of
comparable filters in certain other competitor cat-
alogs. The reason for this is that AVX Filters takes
into account both component and circuit reso-
nances and adjusts the table values such
that the insertion loss will not drop below straight
lines drawn between each data point in a
semilog graph.

A feedthru is a low inductance device, acting as a bypass
feedthru capacitor to ground. It works well with a high imped-
ance load and source. For assured contact, it should be sol-
dered directly to a bulkhead or a connector base.
This adds a series-inductive element to the bypass feedthru
capacitor connected to ground. Because of the inductor, it can
be connected to a low impedance source or load. This filter
may be used to link a low impedance source to a high imped-
ance load, or vice versa, with the feedthru capacitor facing the
high impedance circuit.
This filter contains two feedthru capacitors connected to
ground with an inductor in-between. It presents a low imped-
ance to both the source and load, and has a sharper roll-off
than either the feed-thru or L-section designs. With feedthru
capacitors as outer elements, this filter is best suited for high
impedance load and source applications.
This filter forms a 'T' with two inductors and a feedthru capac-
itor connected to ground. Like the π Filter, it has a sharper roll-
off than a feedthru or an L-section design. With inductors as
outer elements, the T-section is intended for applications with
a low impedance load and source. It also finds application
where transient conditions may occur (EMP, lighting, etc).
