Key Features
- 100K ohm resistance value with 20% tolerance for broad-range analog signal level adjustment
- Carbon film construction providing smooth single-turn (1-turn mechanical, 1-turn electrical) rotation with consistent taper
- Through-hole bracket mount in a compact 11.4x12.5mm body for secure panel-mount PCB installation
- Rated at 50V AC and 0.05W power dissipation suitable for low-power signal control circuits
Applications
The PTV09A-4020S-B104 is used as a user-adjustable control in audio equipment, signal generators, and laboratory instruments where a 100K ohm resistance range provides volume, tone, or level adjustment. Its through-hole bracket mount and vertical shaft actuator suit front-panel controls on enclosures up to 50V AC, enabling direct user interaction with the circuit. Single-turn operation and compact 11.4x12.5mm footprint make it a practical choice for consumer electronics and benchtop equipment prototypes.

Frequently Asked Questions
What resistance value and power rating does PTV09A-4020S-B104 offer?
The PTV09A-4020S-B104 provides a 100K ohm total resistance with a 20% tolerance and is rated at 0.05W (50mW) power dissipation. These parameters are appropriate for low-level signal adjustment circuits operating below 50V AC, such as audio volume controls, filter cutoff adjustments, or bias trim applications.
How does the through-hole bracket mount of PTV09A-4020S-B104 simplify panel installation?
The bracket mount design allows the potentiometer body measuring 11.4x12.5x23.8mm to be bolted or snapped into a panel cutout, providing mechanical support independent of the PCB solder joints. This reduces stress on the through-hole pins during repeated shaft rotation and makes PTV09A-4020S-B104 suitable for front-panel controls in metal or plastic enclosures rated up to 50V AC environments.
In which audio and laboratory instrument applications is PTV09A-4020S-B104 commonly used?
The 100K ohm value and single-turn shaft operation make this potentiometer a standard choice for audio amplifier volume and tone controls, function generator output level adjusters, and DC power supply voltage trim controls. Carbon film construction provides low noise during rotation, which is important for audio signal path applications where wiper noise would appear as audible distortion.
How many mechanical and electrical turns does PTV09A-4020S-B104 provide, and how does this affect resolution?
PTV09A-4020S-B104 provides 1 mechanical turn and 1 electrical turn, meaning the full 100K ohm range spans a single 270-degree rotation arc. Single-turn operation provides moderate adjustment resolution suitable for volume and level controls; for applications requiring finer trimming resolution across a narrow resistance window, a 10-turn cermet trimmer covering the same 100K range would offer approximately 10 times greater angular resolution per ohm.
