The Leading Source for EMI Shielding
Reliable Board, Enclosure and Cable Solutions
electromagnetic radio wave absorbers
Radio frequencies emanating from electronic components such as the
printed circuit board sketch at the right are addressed in three ways:
sometimes no shielding is required; a reflective shield in the form of a
local cover for the components, or the entire electronic enclosure can be
fitted up as a shield; an absorber pad shield which soaks up the RF and
converts it to imperceptible heat energy.
The latter Absorber Shield method deals with the unwanted RF energy
right at the source and prevents re-radiation and reflection of the signals
so that neighboring components are unaffected; also, second, third and
fourth order harmonics are nullified or greatly minimized.

Typical shielding approach allows
reflected radiation to affect neighboring
components.

EMC wave absorber
40MHz TO 5GHz: EA SERIES. The EA series is a high frequency noise
absorber in a range of formulations addressing 40MHz to 5GHz radiations
from electronic components. It has a multi-layered structure of screened
coating matrixes adjusted for discrete impedance matching to absorb
electromagnetic waves at various peak frequencies depending on which
of the seven different constructions is used.
applications:
PCB’s, PCB components, electronic enclosures, shielded boxes, all
microprocessor based electronic, EDP, telecom, scientific, medical,
architectural shielding, RF test chambers, shielded facilities
Noise absorber approach assimilates
radiated frequencies and converts to
imperceptible heat energy.

FOR PCB COMPONENTS AND WIRE CIRCUITS. A quick and easy way to
gain 1 to 2 dB without invasive circuit changes. The EA3200H RF
absorber matrix provides a measurable effect from 40MHz to 5GHz
depending on frequency, existing circuit load, and area covered by the
patch^®. Peak performance is at 3.2GHz to 5.0GHz.
Installs simply by removing protective adhesive liner. Convenient 6.00” x
