Bead

Beads are similar in geometry to toroids, but generally longer in length. For sleeves, wall thickness should be ~12% of diameter to ensure structural integrity as well as to avoid centerless grinding. Their application is specific to attenuating high frequency noise or oscillations (ie. EMI or RFI suppression) on round or flat cables. They may also be supplied SPLIT when assembly over a cable is required (see Figures 1 thru 4).

Marterial (-X): prefix for NiZn (ie. H-980) and suffix for MnZn (ie. SB-980-M20 or 21-049-B)
Thickness: may be adjusted to suit application
Tolerances (dimensional): ±2% (nominal value may vary based on material choice)
Tolerances (impedance, ohms/single turn): -20%
Finishes: edge rounding and parylene coating available
