742792901

Overview

The Würth Elektronik 742792901 is a surface-mount EMI suppression power ferrite bead from the WE-PF series. It features a J-lead 2-SMD package with dimensions of 12.00mm x 12.00mm and a maximum height of 8.00mm. The component provides an impedance of 1.18 kOhms at 100 MHz and supports a rated current of 10A. Its maximum DC resistance is 9 mOhms. It operates within a temperature range of -40°C to +125°C.

Feature Summary

• High current handling capability suitable for power line applications
• J-lead terminal configuration for robust surface mounting
• Designed for effective electromagnetic interference suppression in compact spaces

Applications

• Power supply output filtering
• DC-DC converter noise reduction
• Automotive electronics power lines

Procurement Notes

Verify the specific impedance value and current rating against the latest official datasheet before integration. Confirm that the J-lead footprint matches the target PCB layout requirements. Ensure compliance with RoHS3 standards if required by the end product specifications.

Selection Notes

Select this component when high current capacity and significant impedance are needed in a single-line SMD format. The large 12x12mm package allows for better thermal dissipation compared to smaller beads. Consider the J-lead style for mechanical stability during assembly.

Part Context

This part belongs to the WE-PF series, which specializes in SMD EMI suppression power ferrites. These components are engineered for automotive and industrial applications requiring reliable noise filtering on high-current paths without excessive voltage drop.

Replacement Considerations

Check for direct substitutes within the WE-PF series offering similar 10A ratings and 1.18 kOhm impedance. Verify package compatibility and thermal performance characteristics before swapping.
