EMI1206R-2000

Chip Ferrite Bead Overview

The Delevan EMI1206R-2000 is a surface-mount ferrite chip bead designed for EMI and RFI suppression in electronic 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 exhibits an impedance of 2 kOhms at a test frequency of 100 MHz and a maximum DC resistance of 500 mOhms. It supports a maximum DC current of 200 mA with a tolerance of 25%. The device operates within a temperature range of -55°C to +125°C and is supplied in reel packaging.

Chip Ferrite Bead Feature Summary

• Provides effective attenuation of electromagnetic interference and radio frequency noise in high-speed signal lines.
• Utilizes a compact 1206 surface-mount footprint suitable for automated assembly processes.
• Constructed with robust materials ensuring stable performance across wide industrial temperature variations.

Chip Ferrite Bead Applications

• High-speed data line filtering in portable communication devices
• Power supply input/output decoupling in embedded systems
• Signal integrity enhancement in computer peripheral interfaces

Chip Ferrite Bead Procurement Notes

Verify the specific suffix or tape-and-reel configuration required by your manufacturing equipment before ordering. Confirm that the 200 mA current rating aligns with your circuit's peak load requirements to prevent saturation. Ensure the 1206 package dimensions fit within your PCB layout constraints. Cross-reference the manufacturer part number with distributor catalogs to confirm availability and lead times for production runs.

Chip Ferrite Bead Selection Notes

Select this component when a 2 kOhm impedance value is required at 100 MHz for noise suppression. The 200 mA current handling capability makes it suitable for moderate power applications. Consider the 500 mOhms DC resistance impact on voltage drop in low-voltage circuits. The wide operating temperature range supports deployment in harsh environmental conditions where standard commercial grade parts may fail.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the EMI1206R series from Delevan, specialized for suppressing broadband noise. Ferrite beads function as frequency-dependent resistors, dissipating high-frequency energy as heat while allowing DC and low-frequency signals to pass. This specific model targets applications requiring significant attenuation above 100 MHz without introducing excessive insertion loss at lower frequencies.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other 1206 ferrite beads with 2 kOhm impedance at 100 MHz and similar current ratings. Verify pin compatibility and thermal characteristics when swapping manufacturers. Ensure the replacement maintains the same RoHS compliance status if required by regulatory standards.
