TC33X-1-503E is a 3 mm SMD Trimpot trimming potentiometer manufactured by Bourns with a standard resistance value of 50 kO and continuous rotation design. The device features a resistance tolerance of ±25% standard, with contact resistance variation of 5% maximum and essentially infinite resolution, providing precise adjustment capabilities. It operates over a temperature range of -40°C to +100°C with a temperature coefficient of ±250 ppm/°C, and is rated for 0.1 watt at 70°C with a maximum power rating of 50 VDC. The trimmer offers a minimum adjustment angle of 200° and is compatible with pick-and-place and automatic adjustment equipment, making it ideal for reflow soldering applications in circuit board assembly and calibration tasks requiring reliable, repeatable tuning.
