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.

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.

microprocessor based electronic, EDP, telecom, scientific, medical,

This all-around universal wideband formula is available in a standard

temperature type and a high temperature type (up to 200˚C). Excellent

performance from 40MHz to 5GHz.
