# PTV09A-2020F-A503

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

PTV09A-2020F-A503 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 | End terminal of the resistive element, referenced as Terminal 1 in the taper chart, where Terminal 1-3 is the input voltage across the element and the device is rated for a maximum operating voltage of 20 VDC or 50 VAC (linear and audio). |
| 2 | 2 | passive | Output terminal that the taper chart labels as Terminal 1-2 output voltage, moving along the element as the shaft turns through a 280° ±10° mechanical angle. |
| 3 | 3 | passive | Opposite end terminal of the resistive element, referenced as Terminal 3 in the taper chart, where Terminal 1-3 is the input voltage across the element. |
