74269243461

Overview

The Würth Elektronik part number 74269243461 is a surface-mount EMI suppression ferrite bead from the WE-TMSB series. It features a 0402 [1005 Metric] package and utilizes multi-layer technology for high-speed signal integrity. The component provides an impedance of 460 ohms at its rated frequency and has a DC current rating of 500 mA. Its compact form factor makes it suitable for dense PCB layouts where space is limited.

Feature Summary

• Multi-layer construction for effective EMI suppression in tight spaces
• Designed for high-speed signal and low power line applications
• Suitable for audio, video, and clock line protection

Applications

• General signal lines
• Low power lines
• Audio and video circuits
• Clock lines

Procurement Notes

Verify the specific impedance value and DC current rating against the official datasheet before integration. Confirm that the 0402 package dimensions align with the PCB footprint design. Ensure the operating temperature range meets the system requirements. Check for RoHS and REACH compliance documentation if required by the target market regulations.

Selection Notes

Select this component when space constraints prevent the use of larger ferrite beads or chokes. It is appropriate for filtering noise on sensitive high-speed digital lines. Consider the 500 mA current rating to ensure it does not saturate under maximum load conditions. Evaluate the 460 ohm impedance to confirm it matches the noise frequency spectrum requiring attenuation.

Part Context

This component belongs to the WE-TMSB series, which consists of SMT EMI suppression ferrite beads. These parts are engineered for general signal and low power lines. The series offers a balance between size and performance, targeting applications where traditional through-hole or larger surface-mount solutions are impractical due to board real estate limitations.
