43 SHIELD BEAD
Explanation of Part Numbers:
– Digits 1 & 2 = Product Class
– Digits 3 & 4 = Material Grade
– Last digit 1= Not Burnished 2 = Burnished
– The last digit of the Parylene coated part is a “4,” which is available upon request. The minimum coating thickness beads is 0.005 mm (0.0002″).
Fair-Rite offers a broad selection of ferrite EMI suppression beads with guaranteed minimum impedance specifications.
Our “Shield Bead Kit” (part number 0199000019) contains a selection of these beads.

|Typical Impedance (Ω)|
Suppression beads are controlled for impedances only. Minimum impedance values are specified for the + marked frequencies. The minimum impedance is typically the listed impedance less 20%.
Single turn impedance tests for 73 and 43 material beads are performed on the 4193A Vector Impedance Analyzer. The 61 material beads are tested on the 4291A RF Impedance Analyzer. Beads are tested with the shortest practical wire length.
|Typical Impendance (Ω)|
This NiZn is our most popular ferrite for suppression of conducted EMI from 20 MHz to 250 MHz. This material is also used for inductive applications such as high frequency common-mode chokes.
