Beads on Leads
Shield beads are supplied assembled on tinned copper wire to aid automated circuit assembly.
•
Available materials: 73, 43, and 61.
•
Parts with a “2” as the last digit of the part number are supplied taped and reeled per IEC 286-1 and EIA Standard 296-E.
Inside tape spacing is
52.4±1.5 mm.
These parts can also be supplied not taped and reeled and are then bulk packed. The
last digit of bulk packaged parts is “1”.
• Wires are oxygen free high conductivity copper with a 95/5 tin/lead coating.
•
For performance data on these parts, see page 53 of section “How to Choose Ferrite Components for EMI Suppression”.
•
Beads are controlled for impedance limits only. They are tested for impedance with a single turn, using a Hewlett Packard
HP 4193A Vector Impedance Meter for beads in 73 and 43 material and the HP 4191A RF Impedance Analyzer for 61
material beads.
•
The Expanded Bead-on-Lead EMI Suppressor Kit (part number 0199000010) is available for prototype evaluation.
See page 84.
