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.
Because they are intended for use on external cables in consumer products, Steward has designed the 28A0434-0A2, 28A0592-0A2 and 28A0593-0A2 cores to provide a sleek attractive appearance.
They therefore combine the convenience and ease-of-assembly of snap-on devices, with the look of an overmoulded core.
The new devices provide broad band EMI suppression, with impedances at 25MHz ranging from 111 to 261ohm, and at 300MHz from 449 to 688ohm.
This high performance means that the new cores provide excellent common- and differential-mode EMI suppression with a single cable pass-through: rival solutions generally require customers to wrap cables around and through the core in a multiple-pass configuration to achieve sufficiently high impedance levels.
Designed for use with a range of cable or wire bundle sizes up to 6.5mm in diameter, these new 28-material-based cores feature a secure keyless closure for simple retrofit or post-production assembly.
