782219100

Overview

The Würth Elektronik 782219100 is a surface-mount EMI suppression ferrite bead from the WE-CBA series. It features a 0201 (0603 metric) package with dimensions of 0.60mm x 0.30mm x 0.33mm. The component provides an impedance of 10Ω at 100MHz and has a maximum DC resistance of 0.055Ω. It supports a maximum DC current of 650mA with a tolerance of ±25%. Designed for automotive applications, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides effective electromagnetic interference suppression in compact surface-mount form factors
• Engineered specifically for demanding automotive electronic environments
• Delivers stable electrical performance across extended industrial temperature ranges

Applications

• Automotive electronics systems
• General EMI noise filtering
• Signal line protection

Procurement Notes

Verify the manufacturer part number 782219100 against official Wurth Elektronik documentation to ensure authenticity. Confirm that the received components match the specified 0201 package dimensions and material composition. Check for RoHS compliance markings as indicated in public datasheets. Ensure storage conditions maintain component integrity prior to assembly.

Selection Notes

Select this component when space-constrained automotive designs require EMI filtering. The 0201 footprint suits high-density PCB layouts. The 650mA current rating and low DC resistance are suitable for power or signal lines requiring moderate noise attenuation. Verify thermal stability requirements align with the -55°C to +125°C operating range.

Part Context

This ferrite bead belongs to the WE-CBA series, which focuses on SMT EMI suppression solutions. The series offers various impedance values and package sizes tailored for modern electronic devices. The 782219100 variant specifically addresses the need for small-footprint filtering in automotive and general applications where board real estate is limited.

Replacement Considerations

Consult official Wurth Elektronik cross-reference guides for verified substitutes. Ensure any replacement matches the 0201 package size, 10Ω impedance at 100MHz, and 650mA current rating. Verify that alternative components meet the same automotive qualification standards and temperature specifications.
