Overview
The Würth Elektronik 74269241102 is a surface-mount EMI suppression ferrite bead from the WE-TMSB series. It features a 0402 (1005 metric) package with dimensions of 1.0 mm length, 0.5 mm width, and 0.55 mm height. The component provides an impedance of 1000 Ohms at 100 MHz and supports a maximum current rating of 480 mA. Its maximum DC resistance is specified as 480 mOhms. The device operates within a temperature range of -55°C to +125°C.
Feature Summary
- Provides high impedance for effective electromagnetic interference suppression in signal lines
- Compact 0402 footprint designed for space-constrained surface-mount applications
- Capable of handling rated currents up to 480 mA with low DC resistance
Applications
- Signal line filtering in portable electronic devices
- EMI suppression on data buses in consumer electronics
- Noise reduction in compact circuit boards requiring small form factors
Procurement Notes
Verify the specific impedance value and current rating against the official datasheet before integration. Confirm that the 0402 package dimensions align with your PCB land pattern. Ensure the operating temperature range meets your environmental requirements. Check for any recent product change notices or lifecycle status updates directly from the manufacturer.
Selection Notes
Select this component when high attenuation is required in minimal space. The 1000 Ohm impedance at 100 MHz targets higher frequency noise. The 480 mA current rating suits low-power signal lines rather than power delivery paths. Compare against other WE-TMSB variants if different impedance or current characteristics are needed for the specific circuit design.
Part Context
This part belongs to the WE-TMSB series of surface-mount ferrite beads. These components are engineered for EMI suppression in digital circuits. The series offers various impedance values and package sizes to accommodate different design constraints while maintaining consistent performance standards for noise control in modern electronics.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Consult the manufacturer for equivalent alternatives if this specific part number is unavailable or discontinued.
