DA1206B102R-10

Chip Ferrite Bead Overview

The DA1206B102R-10 is a ferrite bead array manufactured by Laird-Signal Integrity Products. It features four independent lines within a single 1206 (3216 metric) surface-mount package, occupying eight PCB pads. The component provides an impedance of 1000 Ohms at 100 MHz and supports a maximum DC current of 200 mA. Its maximum DC resistance is 800 milliohms. The device operates reliably within a temperature range of -40°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides compact EMI filtering for densely packed printed circuit board designs through a multi-line array configuration.
• Integrates four independent signal paths into a standard 1206 footprint to minimize board space usage.
• Designed for effective noise suppression on power and signal lines in high-density electronic assemblies.

Chip Ferrite Bead Applications

• Filtering electromagnetic interference in densely populated PCB layouts
• Noise suppression for multiple signal lines in portable electronics
• EMI protection for data buses in compact consumer devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm compliance status and packaging details. Ensure the selected variant matches the required impedance and current ratings for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity before procurement.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require filtering multiple signals within a single 1206 footprint. Evaluate the 1000 Ohm impedance at 100 MHz against the noise spectrum of the target circuits. Confirm that the 200 mA current rating exceeds the maximum operating current of the protected lines to prevent saturation or excessive heating during normal operation.
