The 3362R-1-503LF is a 1/4" square Trimpot® trimming potentiometer manufactured by Bourns, designed for precision voltage divider and rheostat applications in sealed, industrial environments. This single-turn cermet device features a 50 kO resistance value with ±10% tolerance, infinite resolution, and a 240° adjustment angle, delivering ±0.05% adjustability in voltage divider mode and ±0.15% in rheostat mode. It operates across -55°C to +125°C with a power rating of 0.50 W at 70°C, 1000 MO minimum insulation resistance at 500 VDC, and 900 VAC dielectric strength at sea level. The potentiometer withstands harsh environments including immersion cleaning, vibration up to 30 G, shock up to 100 G, and 200 rotational cycles, making it ideal for automatic machine adjustment interfaces, industrial control systems, and sealed applications requiring reliable performance in demanding conditions.
