DA1206E300R-00

Chip Ferrite Bead Overview

The DA1206E300R-00 is a four-channel ferrite bead array manufactured by Laird-Signal Integrity Products. It features a 1206 (3216 Metric) surface-mount package with dimensions of 3.20mm x 1.60mm and a maximum height of 0.043 inches (1.10mm). The component provides an impedance of 30 Ohms at 100 MHz per channel, with a rated current of 300mA and a maximum DC resistance of 300 milliohms. Designed for power and signal line filtering, it operates within a temperature range of -55°C to +125°C. This part is currently obsolete.

• Surface-mount construction for automated assembly

Chip Ferrite Bead Applications

• High-density digital interface filtering
• Multi-line data bus protection
• Power distribution network decoupling

Chip Ferrite Bead Procurement Notes

Verify component obsolescence status before design finalization. Confirm that the RoHS non-compliant status aligns with target market regulations. Ensure replacement parts like DA1206E300R-10 are evaluated for pin compatibility and thermal performance equivalence.

Chip Ferrite Bead Selection Notes

Select this component when multi-line EMI suppression is required in space-constrained layouts. Evaluate the 300mA current rating against peak load requirements. Consider the higher DC resistance compared to single-channel beads as it impacts voltage drop across each line.

Chip Ferrite Bead Part Context

This component belongs to the DA series of ferrite bead arrays from Laird-Signal Integrity Products. These arrays consolidate multiple filtering elements to reduce board space usage. The 1206 footprint allows for standard SMT placement while maintaining electrical isolation between channels.
