29F0818-1SR-10

Overview

The Laird-Signal Integrity Products 29F0818-1SR-10 is an eight-line ferrite bead array designed for power line filtering. It features a 16-SMD flat lead package with dimensions of 11.43mm x 4.50mm and a maximum height of 2.92mm. The component provides an impedance of 119 Ohms at 100 MHz, supports a maximum current rating of 6A per line, and has a maximum DC resistance (DCR) of 10 milliohms. It operates within a temperature range of -40°C to 125°C.

Feature Summary

• Eight independent channels integrated into a single surface-mount package
• Flat lead design facilitates high-density board mounting
• Low DC resistance minimizes voltage drop in power distribution networks

Applications

• Multi-rail power supply filtering in electronic systems
• Common-mode noise suppression on parallel power traces
• EMI reduction in compact consumer electronics

Procurement Notes

Verify the specific suffix against official datasheets to confirm impedance values and pin configurations. Ensure the selected variant matches the required current rating and package footprint for the target PCB layout. Confirm RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when multiple power lines require simultaneous noise attenuation in a confined space. The 119 Ohm impedance at 100 MHz targets specific high-frequency interference ranges. Evaluate the 6A current capacity against peak load requirements to prevent saturation or excessive thermal rise during operation.

Part Context

This part belongs to the 29F series of multi-line ferrite arrays from Laird-Signal Integrity Products. These components are engineered to replace discrete beads, saving board area. The 16-SMD flat lead format distinguishes it from standard chip-style beads, offering robust mechanical stability for automated placement.

Replacement Considerations

Direct substitutes include the 29F0818-0SR-10, which shares the same package but offers 75 Ohms impedance. Verify that the lower impedance meets the noise suppression requirements before substitution.
