Key Specifications

This Same Sky PTN24A-B10020K1C rotary potentiometer boasts several key specifications that define its functionality and suitability for various designs. The ‘Taper’ is specified as ‘Reverse Logarithmic’, which is particularly useful in audio applications where a more gradual change in resistance is desired at lower rotation angles, mimicking human hearing perception. The absence of a ‘Detent’ means the shaft rotates smoothly without discrete click stops, offering continuous adjustment. Belonging to the ‘PTN24A Series’, it signifies a family of components with consistent quality and design principles. The ‘No Switch’ attribute indicates that this potentiometer functions solely as a variable resistor without an integrated on/off switch, simplifying its role. ‘No Bushing’ implies a design where the potentiometer is typically mounted directly to a PCB or panel without an additional threaded sleeve for support. With a ‘Power (W)’ rating of ‘0.5’, it can safely dissipate half a watt of power, making it suitable for many low to medium power control circuits. The ‘Size (mm)’ of ’24’ refers to its compact form factor, facilitating integration into space-constrained designs. Its ‘Orientation’ is ‘Vertical’, meaning it is designed to be mounted perpendicular to the PCB surface. The ‘Shaft Style’ is ‘Knurled (18 Teeth)’, providing a secure grip for knobs and ensuring accurate rotational input. ‘Rear Solder Lugs’ for ‘Termination’ offer a robust and reliable connection method for wires or PCB traces. The ‘Mounting Type’ is ‘Through Hole’, ensuring strong mechanical stability on a printed circuit board. A ‘Rotation (°)’ of ‘300’ degrees provides a wide range of adjustment. As a ‘Rotary Potentiometer’ with ‘1 Number of Gangs’, it controls a single electrical channel. It is a ‘1 Number of Turns’ device, meaning the full resistance range is covered within a single rotation. The nominal ‘Resistance (kΩ)’ is ‘100’, offering a substantial range for voltage division or current limiting. A ‘Shaft Length (mm)’ of ’20’ provides ample extension for panel mounting. A ‘Resistance Tolerance (%)’ of ’20’ is standard for many general-purpose potentiometers, indicating the permissible variation from the nominal resistance value. Finally, an ‘Operating Temp Range (°C)’ of ‘-10 ~ 75’ ensures reliable performance across a broad spectrum of environmental conditions.
