DA1206C121R-10

Chip Ferrite Bead Overview

The DA1206C121R-10 is a ferrite bead from the DA series by 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 120 Ohms at 100 MHz, supports a maximum current rating of 300mA, and has a maximum DC resistance of 200 milliohms. It operates within a temperature range of -40°C to 125°C.

Chip Ferrite Bead Feature Summary

• Four-line array configuration for multi-channel noise suppression
• High impedance performance at 100 MHz for effective EMI filtering
• Compact 1206 footprint suitable for space-constrained designs

Chip Ferrite Bead Applications

• Power line filtering in portable electronics
• Signal line protection in data communication interfaces
• EMI suppression in automotive electronic modules

Chip Ferrite Bead Procurement Notes

Verify RoHS compliance status as older variants may differ. Confirm package dimensions and pinout compatibility during PCB layout finalization. Ensure thermal management aligns with the specified operating temperature range. Check for direct replacement availability if supply chain constraints exist.

Chip Ferrite Bead Selection Notes

Select this component when multi-line filtering is required in a single footprint. The 1206 size offers a balance between current handling and board space. Consider the 200 milliohm DCR impact on voltage drop for low-voltage applications. Verify that the 300mA rating meets the peak current demands of the target circuit.

Chip Ferrite Bead Part Context

This part belongs to the DA series of high-current ferrite chip beads. It shares the 1206 form factor with other Laird components but distinguishes itself through its four-line architecture. The series is engineered for robust EMI suppression in dense electronic assemblies requiring multiple filtered channels.

Chip Ferrite Bead Replacement Considerations
