**Microchip** · Temperature and Humidity Sensor · SOT-23

TC1046VNBTR from Microchip, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Input supply voltage. Operating range 2.7V to 4.4V (absolute max 7V). Typical supply current 35 µA (60 µA max). |
