suppression prototyping
Your lab is not complete without a selection of ferrite RFI-EMI suppressors on hand. Helpful
during engineering evaluations, prototyping, emergencies, and eventually for final product
compliance testing and documentation.
The engineering kits shown on page 30 contain a wide assortment of sizes, configurations and
suppression levels for any insertion loss requirements.
The test fixtures shown below are indispensable problem-solving aids, useful in any
laboratory.
When extra samples are required for your project, just a phone call to our customer service
department will have them immediately on the way to you.
empirical test fixtures
A handy R&D/test device for determining if a ferrite suppressor is
feasible in a given situation. With this massive amount of insertion loss
material applied to a circuit, a rough estimate of attenuation effect can
be previewed. Afterwards, a properly configured ferrite assembly can be
determined. Install on any cable data signal circuit by reassembling ferrite
halves within the plastic strap. Even flat ribbon cables pass through the
large opening. Available in our four standard material formulas.
empirical test fixtures
Another variation of the test fixture shown above – the same ferrite core
encased in a heavy-duty hinged nylon plastic enclosure. A handy R&D/
test device for determining if a ferrite suppressor is feasible in a given
situation. With this massive amount of insertion loss material applied
to a circuit, a rough estimate of attenuation effect can be previewed.
Afterwards, a properly configured ferrite assembly can be determined.
Install on any cable data signal circuit by clamping around the cable.
Even flat ribbon cables pass through the large opening. Available in our
four standard material formulas.

IN FULLY ENCLOSED PLASTIC CASE WITH 2.0” (50,8mm) I.D.
Similar to other “CS” Empirical Test Fixtures above, except with a
4.0”
in four standard material formulas.
empirical test fixture
A high impedance R&D/test device for determining if a ferrite suppressor
is feasible in a given situation. Specifically for flat cables and flex-circuits,
with this massive amount of insertion loss material applied to a circuit the
attenuation effect of the wideband ferrite core material can be previewed.
Afterwards, a properly configured ferrite assembly can be determined.
Installs on any cable data signal circuit up to 50-conductors by engaging
the double clamps; quick-release design opens easily. Adhesive foam
pads on bottom allow permanent mounting if desired. Available in our
standard #28 wideband formula for frequencies from 10 MHz to 1 GHz.
