782632102

Overview

The Würth Elektronik 782632102 is a surface-mount EMI suppression ferrite bead from the WE-CBA series. It features an impedance of 1000 ohms at 100 MHz and a maximum DC current rating of 200 mA. The component has a maximum DC resistance of 0.50 ohms and operates within a temperature range of -55°C to +125°C. Its compact 0603 (1.6 mm x 0.8 mm) package is designed for space-constrained applications. The part is AEC-Q200 qualified, ensuring reliability for automotive electronics environments.

Feature Summary

• Provides effective electromagnetic interference suppression through high impedance characteristics
• Automotive-grade qualification ensures reliability in demanding operational environments
• Compact surface-mount footprint facilitates automated assembly and dense circuit board layouts

Applications

• Automotive electronic systems requiring EMI filtering
• Portable consumer electronics with limited board space
• High-frequency signal line noise suppression

Procurement Notes

Verify the specific manufacturer datasheet for the 782632102 to confirm final electrical tolerances and thermal ratings before integration. Ensure that the selected component meets all relevant automotive qualification standards required for your specific application environment. Cross-reference official documentation to validate compatibility with your manufacturing processes and supply chain requirements.

Selection Notes

Select this component when high impedance at 100 MHz is required for EMI suppression in tight spaces. The 200 mA current rating suits low-power signal lines rather than power delivery paths. Consider the 0.50 ohm DC resistance impact on voltage drop. The AEC-Q200 qualification makes it suitable for automotive designs where standard industrial components may not suffice.

Part Context

This ferrite bead belongs to the WE-CBA series, which focuses on small-footprint EMI solutions. The 0603 package size balances performance with PCB real estate efficiency. As a passive component, it functions without external power, relying on material properties to dissipate high-frequency noise energy as heat.

Replacement Considerations

Check for direct substitutes within the same WE-CBA family or other AEC-Q200 qualified ferrite beads from Würth Elektronik. Verify that alternative parts match the 1000 ohm impedance at 100 MHz and the 200 mA current handling capability to ensure functional equivalence.
