742792133

Overview

The Würth Elektronik 742792133 is a high-speed EMI suppression ferrite bead from the WE-CBF series, designed for surface-mount applications. It features a 1206 (3216 metric) package with dimensions of 3.2 mm length, 1.6 mm width, and 1.1 mm height. The component provides an impedance of 600 Ohms at 100 MHz and supports a maximum DC current of 500 mA. It has a maximum DC resistance of 0.3 Ohms and operates within a temperature range of -55°C to +125°C. The part is AEC-Q200 qualified.

Feature Summary

• High-speed EMI suppression capability for sensitive signal lines
• AEC-Q200 automotive qualification ensuring reliability in harsh environments
• Compact 1206 surface-mount footprint for space-constrained designs

Applications

• USB 2.0 interface protection
• IEEE 1394 (FireWire) data line filtering
• LVDS signal integrity enhancement
• RS232 control signal noise reduction

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official datasheet before integration. Confirm that the 1206 package dimensions align with the PCB land pattern requirements. Ensure the operating temperature range meets the environmental specifications of the final assembly. Check for any recent product change notices regarding material composition or manufacturing location.

Selection Notes

Select this component when high attenuation is required for high-speed digital interfaces. The 600 Ohm impedance at 100 MHz makes it suitable for suppressing broadband noise above typical power frequencies. The 500 mA current rating allows use in moderate current signal paths without saturation. Consider the low DC resistance to minimize voltage drop across the protected line.
