29F0318-1SR-10

Overview

The 29F0318-1SR-10 is a multi-line ferrite bead manufactured by Laird-Signal Integrity Products, designed for power line EMI filtering. It features a 6-SMD flat lead surface-mount package with dimensions of 4.83mm x 4.50mm and a maximum height of unspecified in the provided text but typically consistent with the series. The component provides an impedance of 119 Ohms at 100 MHz across three independent lines. It supports a maximum rated current of 6A per line and has a maximum DC resistance (DCR) of 10 milliohms. The device operates within a temperature range of -40°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Provides simultaneous EMI suppression on three independent power lines
• Low DC resistance minimizes voltage drop and power loss
• High current handling capability suitable for dense power distribution networks

Applications

• Multi-rail power supply input filtering
• High-density server backplane decoupling
• Portable electronic device power management units

Procurement Notes

Verify the specific suffix requirements against your bill of materials, as packaging options may vary between tape-and-reel and cut-tape formats. Confirm RoHS3 compliance status if required by your environmental regulations. Ensure the 6A rating aligns with your peak load currents to prevent saturation or excessive heating during operation.

Selection Notes

Select this component when three-phase or triple-rail filtering is required in a compact footprint. The 119 Ohm impedance at 100 MHz targets common noise frequencies in digital circuits. Compare the 10 milliohm DCR against thermal constraints to ensure adequate heat dissipation under continuous 6A loads without exceeding temperature limits.

Part Context

This part belongs to the 29F series of high-current ferrite beads from Laird-Signal Integrity Products. The series is characterized by low-profile SMD packages designed for automated assembly. Similar parts in the lineup vary by line count, impedance values, and current ratings to accommodate diverse power integrity requirements.

Replacement Considerations

Direct substitutes include other Laird 29-series components with matching 3-line configurations and similar impedance characteristics. Verify pinout compatibility and physical dimensions before substitution to ensure board fitment.
