EMI0805R-90

Chip Ferrite Bead Overview

The Delevan EMI0805R-90 is a surface-mount ferrite bead designed for EMI and RFI suppression in electronic circuits. It operates within a temperature range of -55°C to +125°C and utilizes an 0805 (2012 metric) package with dimensions of 2 mm length, 1.25 mm width, and 0.9 mm height. The component exhibits an impedance of 90 Ohms at a test frequency of 100 MHz, with a maximum DC resistance of 100 mOhms and a tolerance of 25%. It supports a maximum DC current of 600 mA and is available in reel, cut tape, and MouseReel packaging formats.

Chip Ferrite Bead Feature Summary

Chip Ferrite Bead Procurement Notes

Verify the specific ordering suffix and packaging configuration when placing orders, as availability may vary between reel, cut tape, and specialized distribution formats. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated products. Ensure that the selected variant matches the required impedance tolerance and current rating specifications for the target application environment.

Chip Ferrite Bead Selection Notes

Select this component based on its 90 Ohm impedance characteristic at 100 MHz and 600 mA current handling capability. The 0805 footprint allows for compact PCB layouts where space is constrained. Consider the low DC resistance value to ensure minimal impact on signal or power delivery efficiency compared to higher-resistance alternatives in similar packages.
