Magnaperm® High Permeability Toroidal Cores are
manufactured with cobalt-based Metglas®
amorphous alloy 2714A for high frequency
applications.
These flat loop toroidal cores offer a unique
combination of ultra-high permeability, high
saturation flux density and extremely low core loss
for electronic component designers.
These properties make Metglas® Magnaperm®
cores
ideal for a diverse range of applications such as:

• EMI common mode filtering
-0.5
• Telecommunications & data communications
interface transformers
• High accuracy current transformers

H, A/m
• High accuracy pulse transformers
• Ground fault protection devices
Benefits
Standard sizes are available from 9.6 mm to
34.1 mm OD and the possibility of manufacturing
custom sizes also exists. Core coatings meeting
UL94V-0 and temperature class F are available
upon request.

• Higher initial permeability – which reduces the
number of turns
• High permeability over a wide range of
operating frequencies
• High attenuation – reduces the need for multi
stage filtering
• Low profile – enabling weight and volume reduction
up to 50%
