Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'AN' against official TE Connectivity documentation to confirm material composition and termination specifications. Ensure that the required impedance tolerance aligns with the standard 25% specification provided in the datasheet. Confirm that the operating environment remains within the specified -55°C to +125°C thermal limits to maintain performance integrity during deployment.

Chip Ferrite Bead Selection Notes

Select this component when a low-impedance path is required for DC signals while attenuating high-frequency noise around 100 MHz. The 800 mA current rating makes it suitable for moderate power lines where saturation must be avoided. Consider the 1206 footprint constraints and ensure PCB layout accommodates the 3.2 mm x 1.6 mm physical dimensions for proper soldering and mechanical stability.

Chip Ferrite Bead Part Context

This part belongs to the BMC series of multilayer ferrite beads manufactured by TE Connectivity Passive Product. It serves as a passive filter component used to suppress unwanted high-frequency signals in electronic assemblies. The product is distinct from other series based on its specific impedance profile and current handling capabilities within the standardized 1206 package format.
