With sizes from 0201 to 3312, having DC resistance as low as 0.01 ohms, peak impedances over 3 ohms, and current carrying capability as high as 10 amps, Laird Technologies chip beads can solve most board-level signal line filtering applications.
EMI and electrical noise can originate at, or affect, almost any device on a circuit board. Ferrite chip beads provide the most widely used, cost-effective, compact EMI filtering option for circuit designers. Ferrite chip beads provide lossy impedance at a variety of impedance and frequency ranges. Compact package sizes, as small as EIA 0201, assist dense circuit board construction and allow the ferrite chip beads to be placed close to the EMI source or receptor.
Peak impedances as over 5000 ohms are available, with low DC resistances (DCR) down to 0.004 ohms, giving designers a wide range of filtering options. High frequency versions to 3 GHz and high current parts up to 10 amps further extend the problem-solving range of these products.
Laird Technologies’ ferrite chip beads are ideal for miniature and portable electronic system devices and digital signal lines. They offer space efficiency with superior EMI noise filtering over a wide frequency range of low to several hundred MHz for broad-band signal interfaces, up to GHz ranges for high frequency signal lines.
With a small footprint and excellent performance retention under bias, Laird Technologies’ ferrite chip beads offer superior impedance versus frequency characteristics that are economical with a broad range of impedance values and current ratings.

Laird Technologies has released 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 SPICE Model has the capability of predicting (with superior accuracy) the real performance of an EMI chip bead actually in circuit operation.
