742861210

Overview

The Würth Elektronik 742861210 is a surface-mount ferrite bead from the WE-CBF HF series, designed for high-frequency noise suppression. It features a 0603 (1608 Metric) package with dimensions of 1.6mm x 0.8mm x 0.95mm. The component provides an impedance of 1000 Ohms at 100 MHz and has a maximum DC current rating of 50 mA. Its DC resistance is specified as 1.8 Ohms. It is suitable for single signal line applications.

Feature Summary

• High-frequency noise attenuation capability
• Compact surface-mount footprint
• Single-line signal protection

Applications

• High-speed data line filtering
• RF circuit noise suppression
• Portable electronic device signal integrity

Procurement Notes

Verify the specific datasheet version to confirm impedance tolerance and thermal characteristics. Ensure the selected component meets the required DC current limits for the target application. Cross-reference the package dimensions with the PCB footprint design to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when space constraints require a 0603 package size. Choose based on the 1000 Ohm impedance requirement at 100 MHz for effective high-frequency damping. Consider the 50 mA current limit when designing circuits with higher power demands, as saturation may occur beyond this threshold.

Part Context

This part belongs to the WE-CBF HF series, which focuses on high-frequency performance in small packages. It complements other EMI suppression components by offering precise impedance profiles for sensitive digital and analog lines within compact consumer and industrial electronics designs.

Replacement Considerations

Check for equivalent 0603 ferrite beads with similar 1000 Ohm @ 100 MHz impedance and 50 mA ratings. Verify that any substitute maintains the same physical dimensions and electrical characteristics to ensure compatibility with existing PCB layouts.
