PT15 0.25w 100Ω To 5MΩ 15mm 100k Potentiometer Through Hole Trimmer Resistor
Quick Detail
Description
- The PT15 Carbon Film Potentiometer is a robust 15mm single-turn trimmer designed for high-precision applications. Built with a durable carbon resistive element and 0.25W power rating, it offers a wide resistance range from 100Ω to 5MΩ with ±20% tolerance and a temperature coefficient of ±300 ppm/°C. Featuring vertical adjustment with hexagonal and arrow-shaped slots, this potentiometer ensures reliable performance and up to 100,000 life cycles.
- Its shaftless design provides maximum flexibility, supporting customized shafts, motor control, or human interface adjustments. Ideal for controlling frequency, motor speed, or light brightness, the PT15 also serves as a dependable position feedback sensor for microcontrollers, making it widely adopted in audio equipment, instrumentation, and industrial automation.
