PTN15-E100DB10-H PTN15-E100DB10-H Trimmer Potentiometer

PTN15-E100DB10-H is a high-quality trimmer potentiometer manufactured by Same Sky, a reputable name in electronic components. This passive component is designed for precise resistance adjustment in various electronic circuits. Trimmer potentiometers, often referred to as trimpots, are miniature variable resistors used for fine-tuning and calibration purposes, typically set once during manufacturing or servicing and not frequently adjusted by the end-user. The PTN15-E100DB10-H belongs to the PTN15 series, indicating a specific design and form factor suitable for through-hole mounting applications, making it a versatile choice for a wide array of electronic designs requiring stable and reliable resistance control.

Key Specifications

The Rotor: D-cut specification indicates the shape of the shaft where a knob or tool would interface. A D-cut shaft provides a secure fit for D-shaped knobs, preventing slippage and ensuring precise adjustments. The Taper: Linear means that the resistance changes uniformly with the rotation of the shaft. This is crucial for applications where a direct and proportional relationship between mechanical rotation and electrical resistance is required, unlike logarithmic tapers used in audio volume controls. The absence of a Detent means the shaft rotates smoothly without discrete click stops, allowing for continuous and fine adjustments. The Series: PTN15 identifies this component as part of Same Sky’s PTN15 product family, which often implies consistent form factors and performance characteristics across the series. The lack of a Bushing suggests that the potentiometer is designed for panel mounting directly via its body or PCB, rather than requiring a threaded bushing for secure attachment to a panel. With a Power (W): 0.15, this potentiometer can safely dissipate up to 0.15 watts, which is a standard power rating for trimmer potentiometers used in low-power signal conditioning and calibration circuits. The Size (mm): 15 refers to the approximate diameter or main dimension of the component, indicating its compact footprint suitable for space-constrained designs. The Orientation: Vertical specifies that the potentiometer is designed to be mounted vertically on a PCB, with its adjustment screw or shaft pointing upwards. The Shaft Style: Shaftless indicates that it typically requires a screwdriver or similar tool for adjustment, rather than having an extended shaft for a knob. Termination: Straight PC Pins means it features straight pins for easy insertion into a printed circuit board. Its Mounting Type: Through Hole ensures robust mechanical and electrical connections to the PCB. The Rotation (°): 265 specifies the total mechanical travel of the rotor from one end stop to the other, allowing for a broad range of adjustment. The Component Type: Trimmer Potentiometer clearly defines its function as a variable resistor for fine-tuning. A Resistance (kΩ): 100 indicates its maximum nominal resistance value, making it suitable for a wide range of circuit designs. The Resistance Tolerance (%): 10 specifies that the actual resistance value will be within ±10% of the nominal 100kΩ, which is a common tolerance for trimmer potentiometers. Finally, an Operating Temp Range (°C): -10 ~ 70 ensures reliable performance across a broad range of environmental conditions typically encountered in industrial and consumer electronics.

Features and Benefits

• Reliable Same Sky Quality: Manufactured by Same Sky, this component benefits from established quality control processes, ensuring consistent performance and longevity in your electronic designs.

Typical Applications

The PTN15-E100DB10-H trimmer potentiometer is highly versatile and finds application in numerous electronic systems requiring precise, infrequent adjustments. One common application is in sensor calibration circuits, where it can be used to fine-tune the output of a sensor (e.g., temperature, light, or pressure sensor) to match a specific reference or to compensate for manufacturing tolerances. Another key use case is in audio equipment for setting bias points in amplifier stages or adjusting equalization parameters during the manufacturing process, ensuring optimal sound performance. In power supply units, this potentiometer can be employed for precise voltage or current limit adjustments, allowing for fine-tuning of output parameters to meet specific load requirements or safety standards. Furthermore, it is frequently utilized in timing circuits and oscillators to accurately set oscillation frequencies or delay times, which is critical in applications like industrial control systems or communication devices. Finally, in test and measurement equipment, it serves as a crucial component for calibrating internal reference voltages or current sources, ensuring the accuracy and reliability of the instruments themselves.
