CHARACTERISTICS
Description: Wide-band wire-wound beads
Applications: Used for EMI and RA filtering applications. Also
used in RF circuits to subdue “parasitic oscillation” at VHF
and UHF
Testing: Impedance is tested on an HP4287A at 100 MHz
Miscellaneous: RoHS Compliant available.
Additional Information: Additional electrical & physical
information available upon request
Samples available. See website for ordering information.
