**BOURNS** · Potentiometers, Variable Resistors · THT

PTV09A-4020S-A104 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 resistive element, shown as terminal 1 on the schematic; the element is rated 1 kΩ to 1 MΩ with a maximum operating voltage of 20 VDC / 50 VAC and 0.05 W power rating. |
| 2 | 2 | passive | Wiper (output) terminal, labelled 'Terminal 1-2 Output Voltage' on the taper graphs; sliding noise is 100 mV max. |
| 3 | 3 | passive | Other end terminal of the resistive element, labelled 'Terminal 1-3 Input Voltage' on the taper graphs; subject to the same 20 VDC / 50 VAC maximum operating voltage and 0.05 W power rating. |
