1.2 HDC3021 in WSON

The HDC3021 is pin-to-pin compatible with the HDC3020. Unlike the HDC3020, the sensor opening is protected by a factory-installed polyimide cover tape. The tape protects the humidity sensor element from pollutants that can be produced as part of the manufacturing process, such as surface mount technology (SMT) assembly, printed circuit board (PCB) wash, and conformal coating. The tape must be removed after the final stages of assembly for accurate measurement of relative humidity in the ambient environment.
