Ferrite disks stick to suppression
Steward has a new range of ferrite disks and plates it claims will significantly simplify the elimination of radiated and inductively coupled electromagnetic interference.
Steward has a new range of ferrite disks and plates it claims will significantly simplify the elimination of radiated and inductively coupled electromagnetic interference (EMI) The new disks and plates also provide a fast and reliable method for identifying EMI problems in prototype circuits, as well as helping to transfer heat from active components

Ferrites fit flat cables
A new range of ferrite EMI suppression cores is specifically designed for flat flex and IDC ribbon cables, giving designers more choice to optimise core size and impedance for these types of cables.
Common-mode chokes handle higher currents
The CM41 range of miniature ultra-high-current ferrite common mode chokes are rated for up to 55A of continuous operating current.
Available in a range of sizes, the disks and plates are known as 'poker chips' because of their appearance.
The parts can be used either as inductively coupled components (to reduce ringing and signal overshoot) or as EMI shields mounted directly on PCB components and traces.
Double-sided adhesive allows the disks and plates to be quickly mounted in the volume production of new designs or the retrofitting of existing products.
In addition, Steward offers versions of the disks and plates with removable and reusable adhesive that allow designers to perform 'trial and error' testing for the rapid identification of potential problems.
Two families of parts are available in the new 'poker chip' range.
M-prefix devices are optimised for applications up to 200MHz, and H-prefix offer enhanced performance above 200MHz.
Circular disks range in diameter from 16.51 to 35.56mm and have thickness options of 1.27, 1.91 and 2.54mm.
The square plates have dimensions of either 19.30 or 26.42mm2 and thicknesses of 1.27 and 1.91mm.
Custom shapes, sizes and thicknesses can also be supplied.
