EMI0805R-120

Chip Ferrite Bead Overview

The Delevan EMI0805R-120 is a surface-mount ferrite bead designed for EMI/RFI suppression in electronic circuits. It features an 0805 (2012 Metric) package size and utilizes multi-layer ferrite technology to provide robust noise attenuation. The component exhibits an impedance of 120 Ohms at a frequency of 100 MHz, ensuring effective signal filtering in high-frequency applications. It supports a maximum current rating of 500 mA with a low DC resistance of 150 mOhm. The device operates reliably within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Procurement Notes

Verify the specific suffix designation against official API Delevan documentation to confirm termination style and material composition. Ensure that the selected variant meets the required impedance tolerance and current carrying capacity for the target application. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity. Check for compliance certifications such as RoHS status if required by the end product specifications.

Chip Ferrite Bead Selection Notes

Select this component when a 120 Ohm impedance at 100 MHz is required for noise suppression in 0805 packages. Consider the 500 mA current rating and 150 mOhm DC resistance for power integrity analysis. Evaluate the -55°C to +125°C operating range against environmental conditions. Compare alternative ferrite beads from the same series if different impedance values or current ratings are needed.
