DA1206D301R-10

Chip Ferrite Bead Overview

The DA1206D301R-10 is a ferrite bead chip from Laird-Signal Integrity Products, designed for EMI filtering in power and signal lines. It features a 1206 (3216 metric) surface-mount package with four independent lines. The component provides an impedance of 300 Ohms at 100 MHz and supports a maximum current rating of 400mA. Its maximum DC resistance is 400 milliohms, and it operates within a temperature range of -40°C to 125°C.

Chip Ferrite Bead Feature Summary

• Four-line array configuration for multi-signal filtering
• High impedance performance at 100 MHz
• Compact 1206 surface-mount footprint

Chip Ferrite Bead Applications

• Power line noise suppression
• Signal line EMI filtering
• Multi-channel data bus protection

Chip Ferrite Bead Procurement Notes

Verify the specific suffix against official datasheets to confirm RoHS compliance status, as historical variants may differ. Confirm the manufacturer's current production status before finalizing procurement plans. Ensure compatibility with standard 1206 footprints during PCB layout. Cross-reference part numbers with authorized distributors to avoid obsolete stock.

Chip Ferrite Bead Selection Notes

Select this component when multi-line filtering is required in a compact space. The four-line design allows simultaneous suppression across multiple channels. Evaluate the 400mA current rating against peak load requirements. Consider the 300 Ohm impedance value relative to target noise frequencies. Verify thermal management capabilities within the specified operating temperature range.

Chip Ferrite Bead Part Context

This part belongs to the DA series of ferrite beads, characterized by multi-line array configurations. It shares the 1206 package dimensions with other high-current variants but distinguishes itself through its four-line architecture. The series targets applications requiring dense packaging and simultaneous noise reduction across multiple conductors.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include DA1206C121R-10 for similar form factors. Alternative options involve BLA31BD121SN4D from Murata Electronics for comparable specifications.
