742692004

Overview

The Würth Elektronik 742692004 is a WE-TMSB series SMD EMI suppression ferrite bead in a 0201 (0603 metric) package. It offers an impedance of 240 Ohms at a test frequency of 100 MHz with a maximum DC current rating of 200 mA. The component features a maximum DC resistance of 150 mOhms and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Tiny multilayer construction optimized for high noise suppression relative to physical size
• Designed for general EMI filtering in signal and low power lines
• Suitable for miniaturization requirements in compact electronic designs

Applications

• Audio signal line filtering
• Clock circuit noise suppression
• Video application interference reduction

Procurement Notes

Verify the specific impedance value and current rating against the official datasheet before procurement, as these parameters are critical for EMI performance. Confirm the 0201 package dimensions match the PCB footprint requirements. Ensure the operating temperature range meets the environmental conditions of the target application.

Selection Notes

Select this component when space constraints necessitate a 0201 footprint while requiring effective high-frequency noise attenuation. Consider the 200 mA current limit for power handling capabilities. Evaluate the 240 Ohm impedance profile against the specific noise frequencies present in the signal or power line to ensure adequate suppression effectiveness.

Part Context

This part belongs to the WE-TMSB series, which consists of tiny multilayer suppression beads. The series is characterized by a wide impedance range from 10 Ohms to 300 Ohms, providing versatile options for EMI mitigation in small form factor electronics.

Replacement Considerations

Check for direct substitutes within the same WE-TMSB series that offer compatible impedance and current ratings. Verify that any alternative component maintains the 0201 package dimensions and similar thermal characteristics.
