Overview
The Würth Elektronik 742792012 is a surface-mount EMI suppression ferrite bead from the WE-CBF series, housed in an 0805 package. It provides an impedance of 33 Ohms at 100 MHz with a maximum DC resistance of 0.008 Ohms and a rated current of 4 Amperes. The component operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive standards.
Feature Summary
- High current handling capability suitable for power line filtering applications
- Automotive grade reliability certified under AEC-Q200 standards
- Compact 0805 surface mount footprint for space-constrained designs
Applications
- EMI suppression on high-current power lines
- Automotive electronic circuit protection
- Signal integrity enhancement in noisy environments
Procurement Notes
Verify the specific datasheet version and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the 0805 package dimensions and terminal configurations match your PCB layout requirements. Ensure the 4A current rating aligns with your application's peak load conditions to prevent saturation or thermal issues during operation.
Selection Notes
Select this component when high current capacity is required alongside effective EMI filtering in a compact form factor. The low DC resistance minimizes voltage drop and power loss in power delivery networks. Consider the 33 Ohm impedance profile at 100 MHz to ensure adequate attenuation for target noise frequencies while maintaining signal integrity for adjacent circuits.
Part Context
This part belongs to the WE-CBF series of SMD EMI suppression ferrite beads designed for robust performance in demanding environments. The series offers various impedance and current ratings across multiple package sizes to support diverse filtering needs in consumer, industrial, and automotive electronics.
Replacement Considerations
Consult official Wurth Elektronik documentation for verified cross-reference part numbers within the WE-CBF family that match specific impedance and current requirements.
