The 89PR200LF is a Model 89 multiturn cermet trimming potentiometer housed in a 3/4" rectangular package with 20 turns of nominal electrical travel. It features a standard resistance range from 10 ohms to 2 megohms with ±10% tolerance (±20% for resistances below 100 ohms), and supports a maximum input voltage of 200 Vdc or rms with a power rating of 0.75 watts at 85°C. The device offers essentially infinite resolution with a maximum contact resistance variation of 1% or 1 ohm (whichever is greater), and includes mechanical stops with clutch action at both ends for reliable operation. Operating over a temperature range of -55°C to +125°C with a temperature coefficient of ±100 ppm/°C, the 89PR200LF is designed for precision adjustment applications in instrumentation, test equipment, and industrial control systems where fine tuning and long-term stability are required.
