PTN10-E25SB20 PTN10-E25SB20 Trimmer Potentiometer

PTN10-E25SB20 is a high-quality single-turn trimmer potentiometer manufactured by Same Sky, a reputable name in electronic components. This passive component is designed for precise resistance adjustment in a wide array of 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 rarely adjusted by the end-user. The PTN10-E25SB20, with its compact 10mm size and vertical orientation, is ideal for space-constrained applications requiring reliable and stable resistance control. Its design focuses on ease of integration into printed circuit boards (PCBs) through its straight PC pins and through-hole mounting, ensuring a robust connection for long-term performance.

Key Specifications

The PTN10-E25SB20 boasts several critical specifications that define its performance and suitability for various applications. The Resistance of 25 kΩ indicates the maximum resistance value achievable, making it suitable for circuits requiring moderate resistance adjustments. A Resistance Tolerance of 20% specifies the permissible deviation from this nominal value, which is standard for many trimmer applications where exact precision isn’t paramount but stable adjustment is. The Power (W) rating of 0.15W denotes the maximum power the component can safely dissipate without damage, a crucial factor for ensuring circuit reliability and preventing overheating. Its Size (mm) of 10mm refers to the physical dimension of the component, highlighting its compact footprint ideal for miniaturized electronic designs. The Operating Temperature Range of -10 ~ 70 °C specifies the environmental conditions under which the potentiometer is designed to function reliably, covering a broad spectrum of typical industrial and commercial applications. The Rotation (°) of 235° indicates the total mechanical travel of the rotor, providing a good range for fine adjustments. The Number of Turns is 1, signifying it’s a single-turn device, which is simpler and quicker to adjust compared to multi-turn trimmers, suitable for applications where a single, quick calibration is sufficient. The Rotor type is Screwdriver, meaning adjustments are made using a standard screwdriver, ensuring secure and precise setting. The Taper is Linear, which means the resistance changes proportionally with the angle of rotation, offering predictable and straightforward adjustment characteristics. The Mounting Type is Through Hole, providing a strong mechanical and electrical connection to the PCB, enhancing durability. Finally, the Termination is Straight PC Pins, simplifying the soldering process and ensuring compatibility with standard PCB layouts.
