742792907

Overview

The Würth Elektronik 742792907 is a surface-mount power ferrite bead from the WE-PF series, designed for EMI suppression in high-current environments. It features a J-lead package and utilizes NiZn core material. The component exhibits an impedance of 240 ohms at 100 MHz and supports a DC current rating of 6 A. Its maximum DC resistance is 0.02 ohms, ensuring minimal signal loss while effectively attenuating electromagnetic interference.

Feature Summary

• Magnetically shielded construction to prevent external field interference
• Suitable for high-current applications up to 6 A
• NiZn core material optimized for EMI suppression

Applications

• Switch mode power supplies
• Power electronics circuits
• High-current signal lines

Procurement Notes

Verify the specific package type and lead configuration against the official datasheet before integration. Confirm that the 6 A current rating aligns with your circuit's thermal requirements. Ensure the 240 ohm impedance at 100 MHz meets your EMI filtering specifications. Cross-reference the manufacturer part number to avoid counterfeit components.

Selection Notes

Select this component when magnetic shielding is required to protect sensitive traces from external noise or to contain emissions. The low DC resistance makes it suitable for power rails where voltage drop must be minimized. Consider the operating temperature range and physical footprint constraints during PCB layout planning.

Part Context

This component belongs to the WE-PF series, which specializes in surface-mount power ferrite beads. These parts are engineered for robust performance in demanding electronic environments, offering reliable EMI suppression without significant impact on DC signal integrity.

Replacement Considerations

Consult official Wurth Elektronik documentation for verified substitute part numbers within the WE-PF series or compatible families. Ensure any replacement matches the 240 ohm impedance, 6 A rating, and J-lead package dimensions.
