29F0430-2SR

Overview

The Laird-Signal Integrity Products 29F0430-2SR is a multi-hole core common mode choke designed for surface mount applications. It features an 8-SMD, flat lead package with dimensions of 0.428 inches in length and width (10.87mm x 10.87mm) and a maximum height of 0.280 inches (7.11mm). The component provides an impedance of 200 Ohms at a test frequency of 100 MHz and supports a current rating of 8 Amperes. It has four lines and a maximum DC resistance of 10 milliohms.

Feature Summary

• Multi-line array configuration utilizing multi-hole core technology for effective noise suppression
• Surface mount design compatible with automated assembly processes
• High current handling capability suitable for power line filtering applications

Applications

• Power line EMI filtering in electronic circuits
• Common mode noise suppression in signal integrity management
• RFI/EMI mitigation in high-current power distribution systems

Procurement Notes

Verify the specific suffix requirements when ordering, as the base model may differ from RoHS-compliant variants like the -10 suffix. Confirm package type availability, as it is typically supplied in cut tape or reel formats. Ensure compatibility with existing footprint designs given the specific 8-SMD flat lead dimensions. Check for obsolescence status as product lifecycles may change.

Selection Notes

Select this component when a 200 Ohm impedance at 100 MHz is required for common mode noise reduction. The 8A current rating makes it suitable for power lines carrying significant load. Consider the 8-SMD flat lead package for board space constraints. Verify thermal performance within the -40°C to 125°C operating range for your specific environment.

Part Context

This part belongs to the Laird 29 series of common mode chokes. It is distinct from similar models like the 29F0430-4SR-10, which offers higher impedance and current ratings. The 29F0430-2SR is specifically characterized by its 200 Ohm impedance and 8A rating, differentiating it from lower current or different impedance options in the same family.

Replacement Considerations

Direct substitutes include the 29F0430-2SR-10 variant, which maintains identical electrical characteristics but complies with RoHS3 regulations. Verify pinout and mechanical dimensions match before substitution.
