Overview
The Würth Elektronik part number 742792643 is a Surface Mount Device (SMD) EMI suppression ferrite bead belonging to the WE-CBF series. It utilizes a 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component exhibits an impedance of 470 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current rating of 400 mA and has a maximum DC resistance of 0.35 Ohms. The operational temperature range spans from -55°C to +125°C.
Feature Summary
- Provides high impedance for effective electromagnetic interference (EMI) attenuation in signal lines.
- Complies with AEC-Q200 automotive qualification standards for reliability.
- Features a compact SMD footprint suitable for space-constrained printed circuit board layouts.
Applications
- Automotive electronics systems requiring AEC-Q200 compliance
- High-speed data line filtering in consumer electronics
- Power supply output filtering for noise suppression
Procurement Notes
Verify the specific impedance value against the manufacturer datasheet, as distributor listings may vary between 40 Ohms and 470 Ohms for similar suffixes. Confirm the package type is strictly 0603 SMD. Ensure the selected variant meets the required DC current rating of 400 mA for the target application circuit design.
Selection Notes
Select this component when high attenuation is required at 100 MHz within a limited board area. The 470 Ohm impedance offers significant noise reduction compared to lower values. Consider the 400 mA current limit to prevent saturation. The wide temperature range ensures stability in harsh environments without derating issues.
Part Context
This ferrite bead is part of the WE-CBF series, designed specifically for surface mount assembly. It serves as a passive component for suppressing high-frequency noise in electronic circuits. The series is characterized by its small form factor and robust construction, making it suitable for modern miniaturized electronic devices and automotive applications.
Replacement Considerations
Check for direct substitutes within the WE-CBF series with identical 0603 dimensions and 470 Ohm impedance. Verify that any alternative component maintains the same AEC-Q200 qualification status and 400 mA current rating to ensure functional equivalence in existing designs.
