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

PTV09A-4025F-B103 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 | Terminal 1 is one end of the resistive element, rated with the device maximum operating voltage of 20 VDC / 50 VAC and power rating of 0.05 W (linear and audio). |
| 2 | 2 | passive | Terminal 2 is the wiper (output) terminal, as indicated by the curves labelled 'Terminal 1-2 Output Voltage', and is subject to the same 20 VDC / 50 VAC maximum operating voltage. |
| 3 | 3 | passive | Terminal 3 is the other end of the resistive element, as indicated by the curves labelled 'Terminal 1-3 Input Voltage', and is subject to the same 20 VDC / 50 VAC maximum operating voltage. |
