Checking for live stock

The Bourns PTV09A-4020U-B104 is a small rotary potentiometer used to adjust voltage, signal level, or resistance in low-power electronic circuits. It features a 6 mm-diameter shaft and a resistance of 100 kω, making it suitable for basic tuning and control tasks on PCBs. This part is typically used where space is limited and fine precision is not critical, such as control knobs, calibration points, or user-adjustable settings.

Core Capabilities of the Bourns PTV09A Potentiometer

The potentiometer is rated at 0.05 W and has a resistance tolerance of ±20%, which is common for general-purpose trim and control applications. It is not designed for high-power use, but it performs reliably in signal-level circuits.

Resistance value: 100 kΩ.
Power rating: 0.05 W.
Tolerance: ±20%.
Linear adjustment suitable for basic control.
6 mm diameter shaft.
Compact body for tight layouts.
Through-hole PCB mounting.
Designed for manual rotary adjustment.
Works well in audio circuits and reference voltage adjustment.

Mechanical Design and Mounting

This model features a through-hole mounting style, making it easy to solder directly onto a PCB. The 6 mm round shaft is compatible with standard knobs, allowing direct user adjustment once mounted on a panel or enclosure.

Typical Uses in Electronics Projects

It is especially useful when a fixed resistor is not flexible enough, and manual tuning is required.

Audio volume or tone control
Signal level trimming
Calibration adjustment points
User-controlled settings on small devices
Educational and prototype electronics
