rfi-emi testing aids
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 the previous page 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, just a phone call to our customer service department will have them immediately on the way to you.
EMPIRICAL TEST FIXTURES
With Quick-release Strap

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: #28 for frequencies from 10 MHz to 1 GHz, #33 for frequencies from 1 to 30 MHz, and #25 for peak suppression of interference occurring at 500 to 700 MHz, and #20 for Bluetooth™ microwave applications.
EMPIRICAL TEST FIXTURES
In Fully Enclosed Plastic Case

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: #28 for frequencies from 10 MHz to 1 GHz, #33 for frequencies from 1 to 30 MHz, and #25 for peak suppression of interference occurring at 500 to 700 MHz, and #20 for Bluetooth™ microwave applications.
SPECIAL PURPOSE LARGE TOROID CLAMP
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" (101,6mm) O.D. and a 2.0" (50,8mm) I.D. ferrite core. Available in four standard material formulas.
EMPIRICAL TEST FIXTURE
For Flat Cables and Flex-Circuits

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.
All dimensions in inches millimeters ±1.6%, or ±0.005" 0,13 mm minimum

PCB "In Situ" Shield Test Fixture

With this massive amount of insertion loss material introduced in the vicinity of RF emissions from a PCB, a proximate absorber attenuation effect occurs. The combined effect of the ferrite substrate and the EA3200H absorber membrane proves very useful in most R&D situations to determine PCB shielding needs. Afterwards, a properly configured PCB shield can be determined.

Can be attached right on top of circuit components with the dielectric foam liner facing the circuit. Comes with temporary installation straps and one flexible Faraday Cage Shield as alternate retaining methods during testing.

All dimensions in inches millimeters ±1.6%, or ±0.005" 0,13 mm minimum
