Overview
The Würth Elektronik 742792111 is a surface-mount EMI suppression ferrite bead from the WE-CBF series, designed for high-speed signal line filtering. It features a 1206 (3216 metric) package with dimensions of 3.2 mm length, 1.6 mm width, and a maximum height of 1.30 mm. The component provides an impedance of 80 ohms at 100 MHz and supports a maximum rated current of 4 A with a maximum DC resistance of 25 milliohms. It operates within a temperature range of -55°C to +125°C.
Feature Summary
- Provides effective anti-EMI suppression for high-speed signal lines
- Features low DC resistance to minimize signal loss
- Supports direct surface mounting on printed circuit boards
Applications
- High-speed signal line filtering
- General EMI suppression in electronic circuits
Procurement Notes
Verify the specific impedance value and current rating against the official datasheet before procurement, as variations may exist within the product family. Confirm that the 1206 package dimensions align with your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Check for any recent Product Change Notices or lifecycle status updates directly from the manufacturer.
Selection Notes
Select this component when a compact SMD ferrite bead is required for signal integrity protection. The 4 A current rating makes it suitable for applications with higher power signals compared to lower-rated alternatives. The 80 ohm impedance at 100 MHz offers specific attenuation characteristics; verify this matches the noise frequency spectrum of your application. Consider the low DC resistance if voltage drop across the filter is a critical design constraint.
