TC33X-2-502E is a 3 mm surface-mount trimming potentiometer (Trimpot) manufactured by Bourns with a nominal resistance of 5 kO and rotational stop feature. The device features an adjustment angle of 270° ± 20°, resistance tolerance of ±25%, and essentially infinite resolution for precise tuning. It operates over a temperature range of -40°C to +100°C with a power rating of 0.15 watts at 70°C, and exhibits a temperature coefficient of ±250 ppm/°C. The potentiometer is RoHS compliant, recommended for reflow soldering, and compatible with pick-and-place and automatic adjustment equipment, making it ideal for circuit calibration, signal conditioning, and tuning applications in compact electronic assemblies.
