Steward is now releasing a revolutionary new SPICE model for EMI
ferrite chip beads. This new, time saving design aid includes the
de-rating effects of dc bias currents on small ferrite board level
parts. Other 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:
- Capable of indicating a part's performance under Bias up to 5
Amps or full rated current
- Can be used with most any SPICE programs like PSPICE & LTSPICE
- Can quickly switch between different Steward chip bead parts.
- Takes into account unwanted parasitic effects caused by increasing
bias
- "Real World" accuracy for better designs the first time
- Provides quicker designs and faster time-to-market
Steward welcomes the opportunity to assist you with your design and
EMI component needs. Please contact Scott Wooden via
