782851102

Overview

The Würth Elektronik part number 782851102 is a Surface Mount Technology (SMT) EMI suppression ferrite bead belonging to the WE-CBA series. It is housed in an 0805 [2012 Metric] package with dimensions of 0.9 mm height. The component exhibits an impedance of 1000 Ω at 100 MHz and supports a DC current rating of 300 mA. Its DC resistance is specified as 0.35 Ω, and it meets AEC-Q200 automotive qualification standards.

Feature Summary

Provides effective electromagnetic interference (EMI) suppression for high-frequency noise filtering in compact surface-mount designs.
Complies with AEC-Q200 automotive qualification standards, ensuring reliability for demanding electronic environments.

Applications

Automotive electronics systems requiring robust EMI filtering
General-purpose printed circuit board (PCB) noise suppression
High-speed digital signal line protection

Procurement Notes

Verify the specific datasheet version when sourcing to confirm impedance tolerances and thermal characteristics. Ensure compatibility with standard reflow soldering profiles for 0805 packages. Confirm that the 300 mA current rating aligns with the target circuit's operational requirements to prevent saturation or excessive heating during normal use.

Selection Notes

Select this component when space constraints necessitate an 0805 footprint while requiring significant high-frequency attenuation. The low DC resistance minimizes voltage drop in power lines, making it suitable for sensitive signal paths. Consider the 1000 Ω impedance peak relative to the noise frequency spectrum to ensure optimal filtering performance without affecting desired signal integrity.

Part Context

This ferrite bead is part of the WE-CBA series from Würth Elektronik, designed specifically for SMT applications. The series focuses on providing reliable EMI suppression solutions that meet stringent automotive quality standards. It serves as a critical passive component for maintaining signal integrity in modern electronic assemblies where space and performance are prioritized.
