742792691

Overview

The Würth Elektronik 742792691 is a surface-mount EMI suppression ferrite bead from the WE-CBF series, housed in a 0603 (1608 metric) package. It provides an impedance of 1500 Ohms at 100 MHz with a maximum DC resistance of 700 milliohms and a rated current of 50 mA. The component operates within a temperature range of -55°C to +125°C and complies with AEC-Q200 automotive standards.

Feature Summary

• Provides high impedance for effective single-line signal noise suppression
• Compact 0603 surface-mount footprint for space-constrained designs
• Automotive-grade reliability certified under AEC-Q200 standards

Applications

• Single-ended signal line filtering in digital circuits
• EMI suppression in automotive electronic modules
• Noise reduction on data transmission lines

Procurement Notes

Verify the specific impedance value of 1500 Ohms at 100 MHz against design requirements. Confirm the 50 mA current rating suffices for the target application's DC load. Ensure the 0603 package dimensions align with the PCB layout. Check for RoHS compliance documentation if required by regional regulations.

Selection Notes

Select this component when high attenuation is needed for low-current signal lines. The 0603 size offers a balance between performance and board space. Consider the 700 milliohm DC resistance impact on signal integrity. The AEC-Q200 certification makes it suitable for automotive environments requiring robust thermal stability.

Part Context

This part belongs to the WE-CBF series of SMD EMI suppression ferrite beads. The series includes various impedances and packages, such as 0805 and 0402 sizes. These components are designed to suppress electromagnetic interference in high-speed digital and RF applications across consumer and industrial sectors.

Replacement Considerations

Check for direct substitutes within the WE-CBF series with similar 0603 footprints and comparable impedance values. Verify that any alternative meets the same AEC-Q200 qualification and thermal operating range.
