782631141

Overview

The Würth Elektronik 782631141 is a surface-mount EMI suppression ferrite bead from the WE-CBA series. It features a 0603 (1608 metric) package with an impedance of 120 Ω at 100 MHz and a maximum DC current rating of 2 A. The component has a maximum DC resistance of 0.05 Ω and operates within a temperature range of -55 °C to +125 °C. It is certified under AEC-Q200 for automotive applications and complies with RoHS standards.

Feature Summary

• Provides effective electromagnetic interference suppression in compact surface-mount form factors
• Engineered for high-current handling capabilities suitable for power line filtering
• Qualified for automotive electronic systems ensuring reliability under strict environmental conditions

Applications

• Automotive electronics requiring AEC-Q200 compliance
• General-purpose EMI filtering on data and power lines
• Portable devices needing compact noise suppression solutions

Procurement Notes

Verify the specific impedance value and current rating against the official datasheet, as distributor listings may vary or contain conflicting specifications. Confirm the package dimensions match the required footprint. Ensure the supplier provides valid RoHS and AEC-Q200 certification documentation for quality assurance purposes before finalizing procurement.

Selection Notes

Select this component when a low-profile SMD ferrite bead is needed for high-current applications. The 0603 size offers space efficiency while maintaining significant noise attenuation. Consider the 120 Ω impedance profile for target frequency ranges. Verify thermal management requirements given the 2 A current rating and low DC resistance characteristics.
