The 3266P-1-203LF is a 1/4" square Trimpot® trimming potentiometer manufactured by Bourns, designed for precision adjustment in industrial and sealed applications. This multiturn cermet device features a 20 kO standard resistance with ±10% tolerance, infinite resolution, and 12 turns of effective travel for fine adjustment control. The potentiometer operates over a temperature range of -55°C to +125°C with a power rating of 0.25 watts at 70°C, and includes mechanical stops with a wiper idle position and solderable pins for reliable PCB integration. Its sealed construction with standoffs allows thorough PC board washing, making it suitable for demanding industrial environments, instrumentation, and data acquisition systems where precision trimming and environmental robustness are required.
