The 3299Y-1-201LF is a 3/8" square multiturn cermet trimming potentiometer designed for industrial sealed applications requiring precision resistance adjustment. This device features a 200 ohm resistance value with ±10% tolerance, 25 turns of effective travel, and infinite resolution for smooth voltage and resistance adjustability of ±0.01% and ±0.05% respectively. The potentiometer operates across a temperature range of -55°C to +125°C with a power rating of 0.5 watts at 70°C, and includes 100% tin-plated RoHS-compliant terminations for reliable soldering. It is commonly used in instrumentation, signal processing, and industrial control circuits where precise trimming and long-term stability are essential.
