1.4 HDC3022 in WSON

HDCC3022 is pin-to-pin compatible with the HDC3020. This device features an IP67 rated hydrophobic protective PTFE membrane over the sensing element. This filter is intended to be left for the lifetime of the device, and protects with 99.99% filtration efficiency for particles down to 100nm in size. The PTFE filter protects the device from dust, debris and condensation. The filter further protects the device during PCB wash and water submergences when the device is operational. While the HDC3022 is protected from physical debris and liquid, the HDC3022 is still susceptible to gaseous contamination, so do not expose the sensor to volatile chemicals. As board wash contains volatile chemicals, and it is recommended to immediately follow up by washing with DI water and air drying the sensor.
