EMI1206R-1200

Chip Ferrite Bead Overview

The Delevan EMI1206R-1200 is a surface-mount ferrite chip bead designed for EMI and RFI suppression. It features a 1206 (3216 metric) package with dimensions of 3.2 mm length, 1.6 mm width, and 1.1 mm height. The component exhibits an impedance of 1200 Ohms at a test frequency of 100 MHz. It supports a maximum DC current of 200 mA and has a maximum DC resistance of 400 mOhms. The device operates within a temperature range of -55°C to +125°C and carries RoHS3 compliance.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference and radio frequency interference suppression in compact surface-mount form factors.

Chip Ferrite Bead Applications

• High-frequency circuit filtering
• High-Q application signal conditioning

Chip Ferrite Bead Procurement Notes

Verify the specific manufacturer designation, as API Delevan and Delevan are referenced interchangeably for this part number. Confirm RoHS3 compliance status directly with the supplier documentation. Ensure the ordering quantity aligns with the factory pack quantity of 3000 units per reel. Cross-reference the impedance value of 1200 Ohms against schematic requirements to prevent mismatched filtering characteristics.

Chip Ferrite Bead Selection Notes

Select this component when a 1200 Ohm impedance at 100 MHz is required for noise attenuation. The 200 mA current rating dictates suitability for low-power signal lines rather than high-current power rails. The 1206 footprint allows for standard SMT assembly processes. Consider the 400 mOhm DC resistance impact on voltage drop if placed in series with sensitive bias circuits.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the EMI1206R series, which focuses on EMI suppression using ferrite materials. The series complements Delevan's broader portfolio of shielded and unshielded inductors, such as the S1210 and 1812 series, offering specialized solutions for high-reliability electronic filtering applications.
