Overview
The Würth Elektronik 742792692 is a WE-CBF series ferrite chip bead designed for signal line EMI suppression. It features a 0603 (1608 metric) surface mount package with dimensions of 1.60mm x 0.80mm and a maximum height of 1.00mm. The component provides an impedance of 1.8 kOhms at 100 MHz and supports a maximum DC current of 50mA. Its maximum DC resistance is 800 milliohms. It operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.
Feature Summary
- Provides high impedance for effective electromagnetic interference suppression on single signal lines
- Compact 0603 surface mount footprint suitable for space-constrained PCB layouts
- AEC-Q200 qualified for automotive electronics reliability standards
Applications
- Automotive infotainment system signal lines
- High-speed data interface noise filtering
- Consumer electronics EMI suppression
Procurement Notes
Verify the specific suffix and packaging configuration against the manufacturer's datasheet before ordering. Confirm that the 50mA current rating meets the circuit requirements to prevent saturation. Ensure the 0603 package size aligns with the PCB land pattern design. Check for RoHS compliance status if required by project specifications.
Selection Notes
Select this component when high impedance is required for low-current signal lines in compact designs. The 0603 package offers a balance between performance and board space. Consider the 50mA current limit carefully, as exceeding it may reduce effectiveness. The AEC-Q200 qualification makes it suitable for automotive applications requiring robust reliability.
Part Context
This part belongs to the Würth Elektronik WE-CBF series of ferrite chip beads. The series includes various impedances and packages tailored for different frequency ranges and current levels. The 742792692 specifically targets high-impedance needs in small form factors, complementing other series members with different electrical characteristics.
Replacement Considerations
Check for direct substitutes within the WE-CBF series with similar impedance and package dimensions. Verify that any replacement maintains the 50mA current rating and AEC-Q200 qualification if used in automotive contexts. Ensure the new part fits the existing 0603 footprint without modification.
