29F0418-1SR

Overview

The 29F0418-1SR is a ferrite bead and chip filter designed for power line applications. It features an 8-SMD, flat lead package with dimensions of 6.10mm x 4.50mm and a maximum height of 4.19mm. The component provides 119 Ohms impedance at 100 MHz across four lines. It supports a maximum current rating of 6A with a maximum DC resistance of 10 milliohms. Operating temperatures range from -40°C to 125°C.

Feature Summary

• Provides electromagnetic interference filtering for power lines
• Multi-line configuration with four independent channels
• Surface mount design for automated assembly

Applications

• Power supply input filtering
• DC bus noise suppression
• High-current signal line protection

Procurement Notes

Verify the specific suffix required for compliance. The base model 29F0418-1SR may be obsolete or non-compliant. Confirm if the -10 suffix variant is necessary for RoHS3 compliance and availability. Check manufacturer documentation for exact ordering part numbers to ensure correct packaging and regulatory status.

Selection Notes

Select this component when multi-line power filtering is required in a compact footprint. Ensure the 6A current rating meets circuit demands. Verify that the 119 Ohm impedance at 100 MHz aligns with target noise frequencies. Consider the 8-SMD package size for board space constraints.
