PTV09A-4020U-B203 from BOURNS, in a THT. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | One end terminal of the carbon resistive element (Terminal 1, the reference for the Terminal 1-2 output and 1-3 input curves); the datasheet gives a maximum operating voltage of 20 VDC / 50 VAC and a power rating of 0.05 W for linear and audio taper. |
| 2 | 2 | passive | Wiper (output) terminal, shown as Terminal 2 and measured as the Terminal 1-2 output voltage; the datasheet gives sliding noise of 100 mV max and residual resistance of 500 ohms or ±1 % max. |
| 3 | 3 | passive | Other end terminal of the carbon resistive element (Terminal 3, the Terminal 1-3 input reference); the datasheet gives a maximum operating voltage of 20 VDC / 50 VAC and a power rating of 0.05 W for linear and audio taper. |
