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.
Existing Spice models are only capable of predicting performance of ferrite chip beads when they are not under any significant operating load.
The new Steward Spice model has the capability of predicting (with superior accuracy) the real performance of an EMI chip bead actually in circuit operation.
Features of the new Steward Spice model include: the ability to indicate a part's performance under bias up to 5A or full rated current; compatibility with most Spice programs like PSpice and LTSpice; easy switching between different Steward chip bead parts; taking into account unwanted parasitic effects caused by increasing bias; "real world" accuracy for better designs the first time; and quicker designs enabling faster time to market.
