742792695

Overview

The Würth Elektronik 742792695 is a surface-mount EMI suppression ferrite bead from the WE-CBF series, housed in a compact 0603 (1608 metric) package. It exhibits an impedance of 2500 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 50 mA. The component features a maximum DC resistance of 1 Ohm and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides effective electromagnetic interference suppression for high-speed digital circuits
• Designed for direct surface mounting on printed circuit boards
• Maintains low DC resistance to minimize signal loss

Applications

• High-speed interfaces including USB 2.0 and IEEE 1394
• LVDS signal line protection
• Control signals and RS232 communication lines

Procurement Notes

Verify the specific suffix code against official manufacturer documentation to confirm exact electrical characteristics and packaging configuration. Ensure the selected variant matches the required impedance tolerance and current rating for the target application circuit design.

Selection Notes

Select this component when space constraints require a 0603 footprint with high impedance performance. Confirm that the 50 mA current rating aligns with the signal line requirements. Evaluate the 1 Ohm DC resistance impact on signal integrity for the specific high-speed interface being protected.

Part Context

This part belongs to the WE-CBF series of multi-layer SMD chip beads. These components are engineered for general EMI suppression in portable electronics and data communication equipment where small form factors and reliable noise filtering are critical design parameters.

Replacement Considerations

Cross-reference with other WE-CBF series parts or equivalent 0603 ferrite beads offering similar 2500 Ohm impedance at 100 MHz. Verify pin compatibility and thermal characteristics before substitution.
