Kemtron Ltd represent and distribute Ferrites for Steward Inc. Established in 1876 Steward is a leading producer of ferrite and related materials used in the electronics, copier, telecommunications, military and automotive industries. Ferrite for EMI suppressor products is nickel zinc and exhibit magnetic properties that are dependent on the frequency at which they loss to frequency is utilised to attenuate interference frequencies where the materials losses are high, yet pass lower bands where data is carried.
are excited. In electronic applications the relation of the magnetic
By changing the ferrite composition, it is possible to alter the loss tangent so that attenuation can be enhanced in selected frequency ranges. Steward offers a family of ferrites with varying compositions to allow the user to select the optimum type for the application. The product line:
Cylindrical EMI suppression ferrites Rectangular EMI suppression ferrites EMI suppression ferrites for connectors EMI suppression ferrites for DIL IC's Common mode power/data line EMI ferrites Power/data line EMI suppression ferrites Split ferrites for round cables Split ferrites for flat cables Multiple turn devices Axial lead ferrites Surface mount EMI ferrites Shown are the more common parts, for a full Steward Catalogue please contact us. Large stocks of most parts are held at our warehouse and available for next day delivery.
