742792092

Overview

The Würth Elektronik 742792092 is a surface-mount EMI suppression ferrite bead from the WE-CBF series. It features an 0805 (2012 metric) package with dimensions of 2.0 mm length, 1.2 mm width, and 0.9 mm height. The component provides an impedance of 2000 Ohms at 100 MHz and supports a maximum DC current of 200 mA. It has a maximum DC resistance of 600 mOhms and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides high attenuation for electromagnetic interference in high-speed signal lines
• Features reliable nickel-tin electrodes for soldering compatibility
• Designed for direct placement on printed circuit boards

Applications

• High-speed data line filtering
• General EMI suppression circuits
• Portable electronic devices

Procurement Notes

Verify the specific impedance value of 2000 Ohms at 100 MHz against design requirements. Confirm the 200 mA current rating is sufficient for the target application. Ensure the 0805 package size fits the PCB footprint. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when high impedance is needed for noise suppression in compact designs. The 0805 form factor balances performance with space constraints. Consider the 600 mOhm DC resistance impact on signal integrity. Evaluate thermal performance within the specified operating temperature range.

Part Context

This part belongs to the WE-CBF series of SMD EMI suppression ferrite beads. The series offers various impedances and package sizes, including 0402, 0603, 1206, and 1210. These components are designed for reliable Ni-Sn electrode termination and reflow soldering processes.

Replacement Considerations

Check for other WE-CBF variants with similar 0805 footprints and comparable impedance values. Verify that alternative parts meet the same current and temperature ratings.
