FERRISHIELD: EMI/RFI Shielding Material - standard series – 50 MHz to 1 GHz

Radio frequencies coming from electronic components such as
PC board are controlled/minimized in three ways:
1. perhaps no shielding is required; 2. 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; 3. 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 nearby components are not affected; also, second-, third- and
fourth-order harmonics are effectively null'd or greatly minimized.
