782763102

Overview

The Würth Elektronik 782763102 is a WE-CBA series surface-mount ferrite bead designed for EMI suppression in signal lines. It features a 1206 (3216 metric) package with dimensions of 3.20mm x 1.60mm and a maximum height of 1.30mm. The component provides an impedance of 1 kOhms at 100 MHz and supports a rated current of 1A. Its DC resistance is maximized at 300 milliohms, ensuring minimal signal loss while effectively attenuating high-frequency noise. It operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.

Feature Summary

• Provides effective electromagnetic interference suppression for single-signal lines through high-impedance characteristics at target frequencies.
• Engineered for high-current applications with a 1A rating and low DC resistance to maintain signal integrity.
• Qualified for automotive environments under the AEC-Q200 standard, ensuring reliability in demanding conditions.
• Utilizes a compact 1206 surface-mount footprint suitable for dense PCB layouts.

Applications

• Automotive electronic systems requiring AEC-Q200 compliant components
• High-speed digital signal line filtering
• Power supply output noise suppression
• General-purpose EMI mitigation in consumer electronics

Procurement Notes

Verify the specific ordering suffix to confirm the exact packaging configuration, such as tape and reel or cut tape, as this affects handling but not electrical performance. Confirm RoHS compliance status via the manufacturer's certificate. Ensure the design accommodates the specified 1206 footprint and thermal requirements for operation up to 125°C. Cross-reference the datasheet for precise impedance curves relevant to your frequency spectrum.

Selection Notes

Select this component when a single-line filter is required for signals carrying up to 1A of current. The 1 kOhm impedance at 100 MHz makes it suitable for suppressing noise in the upper frequency range. Consider the 300 milliohm DC resistance impact on voltage drop if used in power paths. The wide operating temperature range supports deployment in both harsh industrial and automotive environments without derating concerns.

Part Context
