29F0418-0SR-10

Overview

The 29F0418-0SR-10 is a single-line ferrite bead manufactured by Laird-Signal Integrity Products, designed for power line EMI filtering. It features an 8-SMD flat lead package with dimensions of 6.10mm length and 4.50mm width. The component exhibits an impedance of 80 Ohms at 100 MHz and supports a rated current of 6A. Its maximum DC resistance (DCR) is specified at 10 milliohms. The device operates within a temperature range of -40°C to 125°C and complies with RoHS3 standards.

Feature Summary

• Provides electromagnetic interference suppression for power lines through high-frequency impedance characteristics.
• Utilizes a multi-hole core structure integrated into a surface-mountable SMD form factor.
• Engineered for high-current applications with low DC resistance to minimize power loss.

Applications

• Power supply input filtering in electronic equipment
• EMI suppression on high-current signal lines
• Noise reduction in industrial control systems

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct impedance and current ratings. Confirm RoHS3 compliance status if required by project specifications. Check for updated packaging options such as tape and reel or cut tape availability directly from authorized distributors. Ensure the manufacturer part number matches exactly to avoid substitution errors with similar series components.

Selection Notes

Select this component when designing circuits requiring robust power line filtering with a compact footprint. The 80 Ohm impedance at 100 MHz is suitable for suppressing common noise frequencies in switching power supplies. The 6A current rating allows use in higher power stages without saturation. Consider the 8-SMD flat lead package for automated surface mount assembly processes.

Part Context

This component belongs to the 29F series of multi-hole core ferrite beads from Laird-Signal Integrity Products. These parts are distinct from standard chip beads due to their multi-line array capability and larger physical size. The series is commonly used in automotive and industrial applications where high current handling and significant noise attenuation are critical requirements.

Replacement Considerations

Direct substitute: 29F0418-1SR-10. Verify impedance differences (119 Ohms vs 80 Ohms) before replacement.
