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

PTV09A-4025F-B104 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 and forms the 1-3 input voltage reference used in the taper curves (max operating voltage 20 VDC, 50 VAC). |
| 2 | 2 | passive | Terminal 2 is the wiper output, measured as the 1-2 output voltage against the 1-3 input voltage in the taper curves. |
| 3 | 3 | passive | Terminal 3 is the other end of the resistive element and forms the 1-3 input span (max operating voltage 20 VDC, 50 VAC). |
