29F0318-0SR

Overview

The Laird-Signal Integrity Products 29F0318-0SR is a three-line power line ferrite bead designed for surface mount installation. It provides an impedance of 83 ohms at 100 MHz with a maximum DC resistance of 10 milliohms per line. The component supports a rated current of 6A and operates within a temperature range of -40°C to 125°C. Packaged in a 6-SMD, flat lead configuration measuring 10.87mm by 8.33mm, it is intended for high-current EMI filtering applications.

Feature Summary

• Three independent channels provide simultaneous noise suppression for multiple power lines
• Low DC resistance minimizes voltage drop and power loss in high-current circuits
• Flat lead package design facilitates reliable surface mount assembly

Applications

• High-frequency noise reduction on power supply lines
• EMI filtering in electronic systems requiring multi-channel protection
• Signal integrity management in compact surface mount designs

Procurement Notes

Verify the specific manufacturer part number against official datasheets to ensure compatibility with circuit requirements. Confirm that the 83 ohm impedance at 100 MHz aligns with target noise frequencies. Check for RoHS compliance status as indicated in documentation. Ensure the 6A current rating meets system load demands without saturation. Validate package dimensions for PCB footprint accuracy.

Selection Notes

Choose this component when multi-line power filtering is required in a single surface mount package. The 6A rating suits moderate to high current applications. Consider the 83 ohm impedance profile for effective attenuation at 100 MHz. Verify thermal performance within the specified -40°C to 125°C range. Ensure the flat lead package fits available board space constraints.

Part Context

This ferrite bead belongs to Laird's signal integrity product line focused on electromagnetic interference mitigation. It serves as a passive filter element integrated directly into power distribution networks. The component complements other shielding and filtering solutions by addressing conducted noise at the source.
