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

PTV09A-4020F-B105 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 | Resistive element end terminal (Terminal 1, input end of the track); the datasheet gives no pin-specific limit, and the device maximum operating voltage is 20 VDC, 50 VAC with a 0.05 W power rating for linear and audio tapers. |
| 2 | 2 | passive | Wiper terminal (Terminal 2, output); the taper graph plots its output voltage against the input across Terminals 1-3, and the datasheet gives no pin-specific limit beyond the device rating of 20 VDC, 50 VAC. |
| 3 | 3 | passive | Resistive element end terminal (Terminal 3, opposite end of the track from Terminal 1); the datasheet gives no pin-specific limit, and the device maximum operating voltage is 20 VDC, 50 VAC with a 0.05 W power rating for linear and audio tapers. |
