EMI1206R-1000

Chip Ferrite Bead Overview

The Delevan EMI1206R-1000 is a surface-mount ferrite bead designed for EMI and RFI suppression in single-line circuits. 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 provides an impedance of 1000 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 unit operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides effective attenuation of high-frequency electromagnetic interference signals
• Utilizes a compact surface-mount form factor for automated PCB assembly
• Constructed as a single-line suppressor for signal or power line protection

Chip Ferrite Bead Applications

• High-speed digital signal line filtering
• Power supply input noise suppression
• RFI mitigation in communication interfaces

Chip Ferrite Bead Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the manufacturer's official datasheet prior to ordering. Confirm that the 1206 footprint matches the target PCB layout. Ensure the selected supplier sources directly from API Delevan or authorized channels to guarantee component authenticity and traceability.

Chip Ferrite Bead Selection Notes

Select this component when a 1000 Ohm impedance at 100 MHz is required for noise reduction. Verify that the circuit's operating current remains below the 200 mA limit to prevent saturation. Check thermal constraints to ensure operation stays within the specified -55°C to +125°C range during peak load conditions.

Chip Ferrite Bead Part Context

This part belongs to the EMI1206R series of ferrite chip beads manufactured by API Delevan. These components are engineered for general-purpose EMI suppression in electronic assemblies requiring reliable noise control without significant signal degradation at lower frequencies.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other 1206 ferrite beads with 1000 Ohms impedance at 100 MHz, such as the EMI1206R-1000T3000 variant. Cross-referencing with Vishay or Murata equivalents requires matching impedance curves and current ratings.
