Overview
The Würth Elektronik 742792150 is a surface-mount EMI suppression ferrite bead from the WE-CBF series, housed in a 1206 (3216 metric) package. It exhibits an impedance of 80 ohms at a test frequency of 100 MHz and supports a maximum DC current rating of 4 A. The component features a maximum DC resistance of 25 milliohms and operates within a temperature range of -55°C to +125°C.
Feature Summary
- Provides effective electromagnetic interference suppression for high-speed signal lines
- Designed for direct surface mounting on printed circuit boards
- Maintains low DC resistance to minimize power loss in power paths
Applications
- USB 2.0 interface protection
- IEEE 1394 (FireWire) line filtering
- LVDS signal integrity enhancement
- RS232 control signal noise reduction
Procurement Notes
Verify the specific datasheet version corresponding to part number 742792150 to confirm electrical parameters such as impedance tolerance and thermal characteristics. Ensure that the selected packaging format aligns with automated assembly requirements. Cross-reference manufacturer documentation for any recent product change notices or material compliance updates prior to finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring robust EMI filtering for high-current data lines. The 4 A current rating makes it suitable for powering or protecting downstream components in USB and FireWire applications. Evaluate the 1206 footprint against available board space constraints and ensure compatibility with standard SMT reflow soldering profiles specified by the manufacturer.
Part Context
This component belongs to the WE-CBF series of SMD EMI suppression ferrite beads manufactured by Würth Elektronik. These devices are engineered to attenuate high-frequency noise while maintaining signal integrity in digital communication interfaces. The series offers various impedance and current ratings to suit different bandwidth and power requirements across consumer electronics and industrial equipment.
Replacement Considerations
Consult official Wurth Elektronik substitution guides for verified alternatives within the WE-CBF family. Ensure any replacement matches the 1206 package dimensions, 80-ohm impedance at 100 MHz, and 4 A current handling capability. Verify that substitute parts maintain equivalent thermal performance and RoHS compliance standards.
