Overview
The Würth Elektronik 782632181 is a WE-CBA series SMD EMI suppression ferrite bead designed for signal line filtering. It features an impedance of 180 ohms at 100 MHz with a maximum DC resistance of 0.2 ohms and a current rating of 500 mA. The component operates within a temperature range of -55°C to +125°C and meets AEC-Q200 qualification standards. Its compact 0603 (1.6 x 0.8 x 0.8 mm) package facilitates surface mount integration in space-constrained designs.
Feature Summary
- Provides effective electromagnetic interference suppression for high-speed signal lines
- Qualified for automotive applications under AEC-Q200 standards
- Compact surface-mount footprint suitable for dense PCB layouts
Applications
- Automotive infotainment system signal filtering
- High-speed data interface noise suppression
- Consumer electronics EMI mitigation
Procurement Notes
Verify the specific impedance value and current rating against the official datasheet before procurement, as these parameters are critical for circuit performance. Confirm AEC-Q200 compliance requirements if the application involves automotive systems. Ensure the 0603 package dimensions match the design footprint constraints.
Selection Notes
Select this component when signal integrity protection is required for lines carrying up to 500 mA. The 180-ohm impedance at 100 MHz targets specific frequency ranges; verify that this attenuation profile matches the noise spectrum of the target application. Consider the low DC resistance to minimize voltage drop across the filtered line.
Part Context
This part belongs to the WE-CBA series from Würth Elektronik, which specializes in EMI suppression components. The series offers various impedance values and current ratings in standardized packages to support diverse filtering needs across industrial and consumer electronics markets.
Replacement Considerations
Direct substitutes include other WE-CBA series parts with similar impedance and current ratings, such as the 782632101 (100 ohms). Cross-brand replacements require matching the 0603 package, 180-ohm impedance at 100 MHz, and 500 mA current handling capabilities.
