The tube shipping medium is typical for small-quantity prototyping; production volumes often shift to tape-and-reel (check packing option at order). No heatsink is needed at the 1.6 mA quiescent draw, but derate output current if ambient approaches 85°C and the part is driving a heavy load. ## Lifecycle and compliance ROHS3 compliant, so it passes the current EU restriction directive without exemption. The REF02 series has been a staple for decades; Maxim (now part of Analog Devices) continues to manufacture it, and the die is mature and stable.","metaTitle":"REF02CESA+ Voltage Reference, 5V ±1%, 8-SOIC, Active","metaDescription":"Maxim REF02CESA+ series voltage reference: 5V fixed output, ±1% tolerance, 65ppm/°C drift, 12µVp-p noise, -40°C to 85°C, 8-SOIC.
