The TC33X-2-103E is a single-turn surface-mount trimmer potentiometer manufactured by Bourns. Belonging to the Trimpot TC33 series, this component features a nominal resistance of 10kΩ, a resistance tolerance of ±25%, and a rated power of 0.15W at 70°C.
The device utilizes a cermet resistive element, providing reliable resistance adjustment for electronic circuit calibration and tuning applications. Its top-adjustment design allows convenient resistance setting through an adjustment slot, making it suitable for PCB-mounted electronic assemblies requiring precise circuit parameter adjustment.
The TC33X-2-103E features a rotational-stop mechanism with a nominal adjustment angle of 270° ±20°. As a single-turn trimmer potentiometer, it enables convenient manual adjustment of resistance values within its specified range.
Designed for surface-mount technology (SMT), this component features J-lead terminals and a compact 3mm-class footprint. Its approximately 3.80 × 3.60mm face dimensions make it suitable for space-efficient PCB layouts and automated electronic assembly.
The trimmer supports a maximum rated voltage of 50V DC and features a temperature coefficient of ±250ppm/°C. Its operating temperature range extends from -40°C to +100°C, supporting reliable operation in various electronic environments.
The Bourns TC33X-2-103E is suitable for voltage divider adjustment, circuit calibration, reference voltage trimming, feedback adjustment, and other applications requiring adjustable resistance. It provides a practical solution for electronic manufacturers and circuit designers seeking compact and reliable SMD trimmer potentiometers.
The product is supplied in embossed tape-and-reel packaging, with a standard quantity of 2,500 pieces per 7-inch reel, supporting automated pick-and-place equipment and high-volume SMT manufacturing.
