Procurement Notes

Verify the specific suffix designation against official datasheets to confirm dimensional tolerances and material composition. Ensure compatibility with existing cable harness geometries before procurement. Confirm regulatory compliance status such as RoHS3 requirements matches project specifications. Cross-reference manufacturer part numbers to avoid substitution errors during assembly.

Selection Notes

Select this component when managing wide ribbon or flexible circuits requiring uniform magnetic coverage. The rectangular profile ensures consistent contact along flat conductors. Evaluate impedance characteristics against target noise frequencies. Consider physical clearance constraints due to the specific external width and height measurements provided in technical documentation.
