PTN16-D10120K1B1 PTN16-D10120K1B1 Rotary Potentiometer

PTN16-D10120K1B1 is a high-quality single-turn rotary potentiometer manufactured by Same Sky, a reputable name in electronic components. This passive component is designed to provide variable resistance in electronic circuits, making it an essential device for controlling voltage, current, or gain. As a rotary potentiometer, it allows for manual adjustment of its resistance value by rotating a shaft, making it ideal for applications requiring user-interface control. The PTN16 series is known for its compact design and reliable performance, catering to a wide range of industrial and consumer electronics applications where precise and consistent resistance adjustment is critical.

Key Specifications

This Same Sky rotary potentiometer boasts several key specifications that define its functionality and suitability for various designs:

Taper: Linear – A linear taper means that the resistance changes uniformly with the angle of rotation. This is crucial for applications where a direct and proportional relationship between mechanical input and electrical output is desired, such as volume controls or position sensing.

Detent: No Detent – The absence of detents indicates a smooth, continuous rotation. This is beneficial in applications where fine, uninterrupted adjustments are necessary, providing a fluid user experience without tactile clicks at specific positions.

Series: PTN16 – Belonging to the PTN16 series signifies adherence to a specific set of design standards and performance characteristics established by Same Sky, ensuring consistency and compatibility within the product line.

Switch: No – This potentiometer does not integrate an additional switch function. It is purely a resistance-varying device, simplifying its internal structure and focusing solely on its primary function.

Bushing: No Bushing – The lack of a bushing implies a design intended for direct panel mounting or PCB mounting without the need for an additional threaded collar, potentially simplifying assembly in certain applications.

Power (W): 0.125 – With a power rating of 0.125 Watts, this potentiometer can safely dissipate up to 1/8th of a watt. This rating is important for determining the maximum current and voltage it can handle without overheating or damage, making it suitable for low-power control circuits.

Size (mm): 16.5 – The compact 16.5mm size makes this component suitable for space-constrained designs, allowing for integration into smaller devices and PCBs without compromising performance.

Orientation: Vertical – A vertical orientation means the potentiometer is mounted perpendicular to the PCB, which can be advantageous for specific enclosure designs or when optimizing board space.

Shaft Style: Knurled (18 Teeth) – The knurled shaft with 18 teeth is designed for easy attachment of standard control knobs, providing a secure grip and facilitating user interaction for precise adjustments.

Termination: Rear Mount – Rear mount termination implies that the electrical connections are made from the back side of the component, which can be beneficial for specific PCB layouts and wiring configurations.

Mounting Type: Through Hole – Through-hole mounting ensures a robust mechanical connection to the PCB, providing excellent stability and reliability, especially in applications subject to vibration or mechanical stress.

Rotation (°): 300 – A 300-degree rotation range offers a substantial sweep for fine-tuning, allowing for a broad spectrum of resistance adjustments across its full travel.

Number of Gangs: 1 – Being a single-gang potentiometer means it controls one independent resistance path, ideal for single-channel control applications.

Number of Turns: 1 – As a single-turn device, the full resistance range is covered within one rotation of the shaft, offering quick and direct adjustment.

Resistance (kΩ): 10 – A nominal resistance of 10 kΩ (10,000 Ohms) makes it versatile for a wide array of circuits, from audio equipment to industrial controls.

Shaft Length (mm): 20 – The 20mm shaft length provides sufficient protrusion for mounting knobs and integrating into various panel thicknesses, enhancing design flexibility.

Resistance Tolerance (%): 20 – A ±20% resistance tolerance is typical for general-purpose potentiometers, indicating the permissible variation from the nominal 10 kΩ value. This is acceptable for many non-precision applications.

Operating Temp Range (°C): -10 ~ 75 – The operating temperature range of -10°C to 75°C ensures reliable performance across a broad spectrum of environmental conditions, suitable for both indoor and moderately harsh outdoor applications.
