The 3352H-1-203 is a single-turn cermet trimming potentiometer (Trimpot) manufactured by Bourns, featuring a 3/8" round open-frame design with side adjustment. This model offers a 20 kO resistance value with ±20% standard tolerance and infinite resolution through its stable cermet element. The potentiometer operates over a temperature range of -55°C to +125°C with a temperature coefficient of ±100 ppm/°C, and provides adjustability of ±0.05% in voltage divider mode and ±0.25% in rheostat mode. It features a 205° nominal adjustment angle, 0.50 watt power rating at 85°C, and dielectric strength of 500 VAC at sea level. The 3352H-1-203 is ideal for industrial applications requiring precision trimming and calibration in compact spaces, with its very low profile and multiple pin style options making it suitable for PCB integration in instrumentation, data acquisition, and control systems.
