74269242261

Overview

The Würth Elektronik 74269242261 is a surface-mount ferrite bead from the WE-TMSB series, designed for high-current applications. It features a 0402 [1005 Metric] package with an impedance of 260 ohms at 100 MHz and a DC resistance of 0.15 ohms. The component supports a maximum DC current rating of 1 A. It is RoHS compliant and suitable for noise suppression in compact electronic circuits.

Feature Summary

• High current handling capability up to 1 A
• Compact 0402 surface-mount footprint
• Effective noise suppression with 260 ohm impedance

Applications

• Noise filtering in high-current power lines
• EMI suppression in compact consumer electronics
• Signal integrity protection in data interfaces

Procurement Notes

Verify the exact impedance tolerance and DC resistance values against the official manufacturer datasheet before integration. Confirm that the 0402 package dimensions align with your PCB land pattern requirements. Ensure the 1 A current rating meets the operational demands of your specific circuit design to prevent saturation or overheating issues during normal use.

Selection Notes

Select this component when space constraints require a 0402 package but high current capacity is necessary. The 260 ohm impedance provides effective attenuation for high-frequency noise. Compare its current rating against alternative ferrite beads to ensure it handles peak loads without performance degradation. Verify compatibility with automated pick-and-place equipment due to the small form factor.

Part Context

This part belongs to the WE-TMSB series, which focuses on high-current ferrite beads for surface-mount technology. It complements other EMI suppression components by offering robust performance in minimal space. The series is engineered for modern electronics requiring efficient noise control without compromising current carrying capacity.

Replacement Considerations

Check for direct substitutes within the WE-TMSB series with similar impedance and current ratings. Ensure any replacement maintains the 0402 footprint and RoHS compliance. Verify that alternative parts offer comparable DC resistance to avoid changes in circuit efficiency.
