Description:
The WI20 cermet trimmer potentiometer is a versatile and reliable component designed for precise resistance adjustments. Featuring a cermet element, it offers both linear and audio tapers to suit a variety of applications. With a rated power of 0.5W at 70℃, the potentiometer covers a nominal resistance range from 10Ω to 5MΩ, maintaining a tolerance of 10%. It provides an electrical travel of 220° and a total mechanical travel of 250°, ensuring accurate control. The contact resistance variation (CRV) is kept within ≤3%R or 3Ω, ensuring stable performance. This potentiometer operates efficiently across a wide temperature range of -55°C to +125°C, with a temperature coefficient of ±100 ppm/°C. Designed for easy mounting, it supports both PC board and bushing installations. The metal bushing enhances durability, and the unit is sealed to allow for board washing, ensuring long-term reliability and performance in various environments.
