EMI0805R-1000

Chip Ferrite Bead Overview

The Delevan EMI0805R-1000 is a surface-mount ferrite bead designed for EMI and RFI suppression in electronic circuits. This component operates within an impedance range of 1 kOhms at 100 MHz, providing effective noise attenuation across high-frequency bands. It supports a maximum current rating of 300 mA while maintaining a low DC resistance of 350 mOhms to minimize signal loss. The device is housed in an 0805 (2012 Metric) package, suitable for automated PCB assembly processes. It functions reliably across an operating temperature range of -55°C to 125°C, ensuring stability in demanding thermal environments.

Chip Ferrite Bead Feature Summary

• Provides targeted electromagnetic interference suppression through high impedance characteristics at specific frequencies
• Utilizes a compact surface-mount form factor compatible with standard pick-and-place manufacturing equipment
• Maintains stable electrical performance across a wide industrial temperature spectrum

Chip Ferrite Bead Applications

• High-frequency signal line filtering in consumer electronics
• Power supply output noise reduction in portable devices
• Data bus protection against radio frequency interference

Chip Ferrite Bead Procurement Notes

Verify the exact impedance specification and tolerance requirements against the official datasheet before ordering. Confirm that the 0805 package dimensions align with your PCB footprint design. Ensure the 300 mA current rating meets the operational load of your circuit to prevent saturation. Check for RoHS compliance status if required by your manufacturing standards.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require a small surface-mount solution for high-frequency noise control. The 1 kOhm impedance at 100 MHz makes it suitable for suppressing broadband noise above this threshold. Consider the 350 mOhm DC resistance impact on voltage drop if used in low-voltage power lines. Evaluate the 300 mA limit against peak current demands to ensure reliability under transient conditions.

Chip Ferrite Bead Part Context

This ferrite bead belongs to Delevan's EMI series of passive components, which are engineered for effective noise suppression in modern electronic assemblies. The company specializes in magnetic components that address stringent electromagnetic compatibility challenges. These parts are widely utilized in industries requiring reliable filtering solutions for sensitive digital and analog circuits.

Chip Ferrite Bead Replacement Considerations

Direct substitutes must match the 0805 package size, 1 kOhm impedance at 100 MHz, and 300 mA current rating. Verify that alternative components offer comparable DC resistance and temperature stability. Ensure the replacement part maintains similar self-resonant frequency characteristics to preserve filtering effectiveness.
