74269221561

Overview

The Würth Elektronik 74269221561 is a surface-mount ferrite bead from the WE-TMSB series, designed for signal line filtering in compact electronic assemblies. It features a 0201 (0603 metric) package with dimensions of 0.6 mm length and 0.3 mm height. The component provides an impedance of 560 ohms at 100 MHz with a tolerance of ±25%. It supports a DC current rating of 250 mA and has a maximum DC resistance of 0.85 ohms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides high impedance attenuation for high-frequency noise suppression on single signal lines
• Utilizes a wide-band ferrite material characteristic optimized for broadband interference reduction
• Designed for automated surface-mount assembly processes using standard tape and reel packaging

Applications

• High-speed digital signal line filtering in portable consumer electronics
• Noise suppression on data interfaces in compact mobile devices
• EMI mitigation in space-constrained automotive infotainment systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact impedance and tolerance specifications. Ensure the procurement channel sources components directly from authorized distributors to guarantee authenticity. Check for recent Product Change Notifications regarding material or manufacturing site updates. Confirm that the received lot matches the required RoHS and REACH compliance standards for your target market regulations.

Selection Notes

Select this component when board real estate is limited due to its small 0201 footprint. Choose this part if the application requires significant attenuation at 100 MHz while maintaining low DC resistance. Consider the 250 mA current rating to ensure it does not saturate under normal operating conditions. Verify that the operating temperature range meets the environmental requirements of the final product enclosure.

Part Context

This ferrite bead belongs to the WE-TMSB series, which focuses on miniaturized solutions for modern electronics. The series addresses the industry trend toward smaller form factors without compromising electromagnetic compatibility performance. It serves as a critical passive component for maintaining signal integrity in dense circuit layouts where traditional larger filters cannot fit.

Replacement Considerations

Cross-reference with other WE-TMSB variants for different impedance values if the 560 ohm specification is unsuitable. Compare physical dimensions with alternative 0201 ferrite beads from other manufacturers to ensure mechanical compatibility. Verify that substitute parts meet the same thermal and current handling capabilities.
