The industrial temperature range (-40°C to 85°C) means this part can sit on a factory-floor PLC backplane or in an outdoor sensor hub without a heated enclosure. The Tube packaging means this part ships in anti-static tubes of 60 or 75 units (typical QFN tube quantity) — not tape-and-reel, so factor in manual placement or a tube feeder if you're running high-volume pick-and-place. ROHS3 compliant (exemption-free for all ten restricted substances), so it passes EU and UKCA material declarations without an exemption note.","metaTitle":"MAX3421EETJ+ USB Host/Peripheral Controller, SPI, 32-TQFN","metaDescription":"MAX3421EETJ+ USB 2.0 controller with SPI interface, 15mA supply, -40 to 85°C.
