Compliance and supply format
The part is ROHS3 Compliant, which means it meets the EU Restriction of Hazardous Substances directive — a requirement for most commercial and industrial BOMs shipping into Europe or following global environmental standards. It is supplied in Bulk packaging — no tape-and-reel, so the units arrive loose in a bag or tube. This format is typical for engineering samples, low-volume builds, or when you want to avoid the reel surcharge for prototype quantities.
