DESCRIPTION
Cosmic EH81 is an iron filled epoxy molding compound which is supplied in a granular form.

FEATURES
This material flows easily under low pressure and provides good moldability.

APPLICATIONS
The material is good for EMI / RFI shielding, and can be either compression or transfer molded to fabricate core rods and to encapsulate surface mount and axial leaded inductors. This single molded compound eliminates the labor intensive over-under molding.
