74269242111

Overview

The Würth Elektronik 74269242111 is a WE-TMSB series surface-mount ferrite bead designed for wideband noise suppression. It features a 0402 [1005 Metric] package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 110 ohms at 100 MHz and supports a maximum current rating of 1.2 A. Its direct current resistance (DCR) is specified as 0.09 ohms, ensuring minimal signal loss in power lines.

Feature Summary

• Compact 0402 footprint suitable for high-density PCB layouts
• Wide impedance range capability for versatile EMI filtering
• Low DC resistance to maintain power efficiency

Applications

• Power line noise suppression in portable electronics
• Signal integrity protection in data transmission circuits
• EMI filtering for mobile communication devices

Procurement Notes

Verify the specific impedance tolerance and current derating curves against your application requirements before finalizing the design. Confirm that the 0402 package size aligns with your assembly capabilities and soldering profile constraints. Ensure compliance with RoHS directives if required by your target market regulations.

Selection Notes

Select this component when space constraints necessitate a 0402 package while requiring significant noise attenuation at 100 MHz. The 1.2 A current rating makes it suitable for moderate power applications where low DCR is critical. Compare its impedance characteristics against other WE-TMSB variants to ensure optimal frequency response for your specific noise spectrum.

Part Context

This part belongs to the WE-TMSB series of tiny multilayer suppression beads from Würth Elektronik. These components are engineered for wideband noise suppression in compact electronic designs.
