LOSSY, MAGNETICALLY LOADED, MACHINABLE STOCK

Eccosorb MF is a series of rigid magnetically loaded epoxy stock, which can be machined for

use as absorbers, attenuators and terminations in waveguides, coaxial or stripline

applications. With products such as these, it is necessary to be conversant with the dielectric

and magnetic properties of the materials, which are listed in this technical bulletin, the

values given are normalized with respect to free space, see Typical Electrical Properties

table.
