Description
- The 3296W-A Cermet Trimming Potentiometer is a high-precision multiturn adjustable component designed for industrial and professional electronic applications. Built with a fully sealed cermet element, it ensures long-term reliability and stable performance even in demanding environments. Featuring an 8mm vertical adjustment metal shaft and a durable multi-finger wiper, it delivers smooth operation and superior contact resistance variation (CRV).
- With a wide resistance range from 10Ω to 5MΩ, ±10% tolerance, and power rating of 0.5W at 70℃, this potentiometer supports up to 30±2 turns of total mechanical travel, allowing for highly accurate calibration and fine-tuning. Its optional temperature coefficient of ±250 or ±100 ppm/°C further enhances stability, making it ideal for use in instrumentation, communication equipment, power supplies, and other precision control circuits.
