t4U.comKemtron Ltd represent and distribute Ferrites for Steward Inc.
eEstablished in 1876 Steward is a leading producer of ferrite
and related materials used in the electronics, copier,
etelecommunications, military and automotive industries. Ferrite for
hEMI suppressor products is nickel zinc and exhibit magnetic
properties that are dependent on the frequency at which they
Sare excited. In electronic applications the relation of the magnetic
loss to frequency is utilised to attenuate interference frequencies
tawhere the materials losses are high, yet pass lower bands where
data is carried.
aBy changing the ferrite composition, it is possible to alter the loss
tangent so that attenuation can be enhanced in selected frequency
.Dranges. Steward offers a family of ferrites with varying
compositions to allow the user to select the optimum type for the
application.

All impedance values are Net; they are based on the ferrite cores only.
Split ferrites for flat cables are sold as single sides. It is necessary to order two sides to form one set.
Metal or Plastic clips are available for the split ferrites.
To specify Plastic Clip, replace the second character after the dash with “P”. Example: 28S2022-0P0
To specify Metal Clip, replace the second character after the dash with “M”. Example: 28S2022-0M0
