EMI1206R-50

Chip Ferrite Bead Overview

The Delevan EMI1206R-50 is a single-line ferrite chip bead designed for surface mount technology (SMT) applications. It operates within the EMI1206R series and utilizes 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 50 Ohms at a test frequency of 100 MHz. It supports a maximum DC current rating of 600 mA and features a maximum DC resistance (DCR) of 100 mOhms. The device functions reliably across an operating temperature range from -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides electromagnetic interference suppression through high impedance characteristics at specific frequencies
• Designed for surface mount integration into compact electronic circuits
• Constructed as a single-line filter component for signal line protection

Chip Ferrite Bead Applications

• Signal line filtering in portable electronics
• Noise suppression in data communication interfaces
• EMI mitigation in consumer device power or signal paths

Chip Ferrite Bead Procurement Notes

Verify the manufacturer part number EMI1206R-50 against official API Delevan documentation to confirm active status and specifications. Ensure compatibility with SMT assembly processes requiring 1206 footprint alignment. Cross-reference impedance values at 100 MHz and current ratings with system design requirements before procurement.

Chip Ferrite Bead Selection Notes

Select this component when a 50 Ohm impedance at 100 MHz is required for noise suppression. The 600 mA current rating suits moderate current applications. The 1206 package size offers a balance between thermal performance and board space efficiency compared to smaller footprints.

Chip Ferrite Bead Part Context

This component belongs to the EMI1206R series of ferrite beads manufactured by API Delevan. The series includes variants with different impedance values such as EMI1206R-120 and EMI1206R-300, all sharing the same 1206 physical package and general electrical architecture for EMI/RFI suppression.

Chip Ferrite Bead Replacement Considerations

Compatible substitutes include other 1206 ferrite beads with 50 Ohm impedance at 100 MHz and similar current ratings. Verify pinout and thermal characteristics match the original design constraints.
