PTV09A-4020S-B503 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 | Terminal 1 | passive | Terminal 1 is one end of the carbon resistive element, and the datasheet defines the input voltage as measured between Terminal 1 and Terminal 3, with a maximum operating voltage of 20 VDC or 50 VAC and a power rating of 0.05 W for linear and audio tapers. |
| 2 | 2 | passive | Terminal 2 is the output (wiper) terminal, and the taper graphs plot the output voltage measured between Terminal 1 and Terminal 2 against rotational travel. |
| 3 | 3 | passive | Terminal 3 is the other end of the resistive element, forming the input reference with Terminal 1 in the Terminal 1-3 input voltage definition, with a maximum operating voltage of 20 VDC or 50 VAC. |
