Low Pass EMI Filters
the industry’s most complete
line of EMI filters gives you
more style, size, IL performance
and cost alternatives
Solder-In Filters
offer an ideal solution for applications
in critical areas where space does not allow for use
of mounting tools or hardware. Available in C, Pi and
standard L circuit configurations and primarily used in
filtering signal/data lines and AC power lines…
LP3-LP7
Miniature Solder-in
Filters
have a knurled design
allowing them to be pressed into place
creating a reliable mechanical bond making
them an excellent choice for applications
where soldering is undesirable…
LP8-LP11
Spec Spin Filters
are an excellent choice
for applications that require many lines to
be filtered in close proximity to each other
due to their space saving #2-56 threaded
miniature EMI spanner design. These
filters are designed without a hex and do
not require soldering for installation…
LP12
High Current Resin Sealed Filters
are ideal
for use in high current 5 volt logic buss, as well
as ±48 VDC telephone rack buss, high current
switch mode power supplies and DC charging
systems. These filters feature rugged bolt-in
style for easy installation…
LP25-LP26
Hermetically Sealed Filters
feature hermetic
glass seals and high EMI filtering performance
making them highly reliable in the toughest
environmental conditions. These filters are
available with C, L, Pi, T and double T
configurations with MIL-F-15733 and MIL-
F-28861 QPL filters available…
LP27-LP42
Resin Sealed Filters
provide excellent
environmental protection in a rugged case
that is resin sealed at both ends and easily
mounted with a tapped hole or through hole.
These filters are provided in C, L and Pi configurations
with metric threading available…
LP13-LP24
Low Pass EMI Advantages
API Technologies’ Spectrum Control brand
was founded in 1968 as a designer and
manufacturer of Electromagnetic Interference
(EMI) filters. Today, API continues that work,
combining knowledge with excellence.
These many years of experience have
yielded an engineering-driven team that
understands how and where potential EMI
problems exist in an electronic system
and how to best eliminate them. With an
extensive library of standard products and a
willingness to develop an application-specific
custom solution, our customers count on us
to help them satisfy global EMC standards
while meeting demanding design parameters.
Value Added Assemblies
offer flexible
solutions by allowing you to add connectors,
modify terminations or add wire harnesses, there-
by lowering your cost of acquisition and assembly,
reducing your production time/costs and inventory,
all while giving you a filter assembly that meets
your unique design challenges…

Solder-in Filters
Solder-in filters are ideal for use in critical areas where
space does not allow use of mounting tools or hardware.
The solder-in feature also allows installation in unison
with other board mounted components. Primarily used
in filtering signal/data lines and DC power lines.
