29F0818-1SR

Overview

The Laird-Signal Integrity Products 29F0818-1SR is an eight-line power line ferrite bead array designed for surface mount applications. It features a 16-SMD flat lead package with dimensions of 11.43mm x 4.50mm and a maximum height of 0.115 inches (2.92mm). The component provides an impedance of 119 Ohms at 100 MHz and supports a maximum rated current of 6A per line. Its DC resistance is maximized at 10 milliohms, ensuring minimal signal loss while effectively filtering electromagnetic interference in high-current power distribution networks.

Feature Summary

• Eight independent channels integrated into a single compact surface-mount package
• High current handling capability suitable for dense power plane filtering
• Flat lead design facilitates reliable mounting on printed circuit boards

Applications

• Multi-rail power supply filtering in server motherboards
• EMI suppression for high-speed digital logic power lines
• Noise reduction in portable electronic device power architectures

Procurement Notes

Verify the specific suffix designation when sourcing replacements, as variants like -10 may differ in compliance status or packaging. Confirm RoHS3 compliance requirements against project specifications. Ensure the 16-SMD flat lead footprint matches the target PCB layout exactly to avoid mechanical fit issues during assembly.

Selection Notes

Select this component when multiple power rails require simultaneous noise attenuation within a constrained board area. The 6A rating makes it appropriate for main voltage regulation outputs. Compare impedance characteristics against other multi-line arrays to ensure adequate filtering performance at the target frequency range without excessive voltage drop under load.

Part Context

This part belongs to Laird's 29F series of high-current ferrite bead arrays. These components are engineered to replace discrete ferrite beads, saving significant PCB real estate. The series offers various line counts and impedance values to accommodate different power distribution network designs in modern electronics.

Replacement Considerations

Direct substitutes include the 29F0818-1SR-10 variant. Alternative similar parts from other manufacturers should be evaluated for matching impedance, current rating, and physical footprint compatibility.
