BOURNS TC33 Series Trimmer Potentiometer 50K Ohm, Top Adjust, Surface Mount

The BOURNS TC33 Series is a high-precision, 3mm SMD trimming potentiometer designed for reliable performance in modern electronic assemblies. This Trimpot® component is specifically recommended for reflow soldering processes, ensuring compatibility with automated production lines. Its innovative rotor design is fully compatible with both pick-and-place equipment and automatic adjustment systems, facilitating efficient, high-volume manufacturing. For manual calibration, the trimmer can be easily adjusted using a standard H-90 tool.

Engineered for critical applications, this single-turn, top-adjust cermet trimmer delivers essentially infinite resolution, providing fine-grained control over electrical parameters. It features a continuous mechanical adjustment angle of 200° with a minimum adjustment angle, allowing for precise tuning. The compact 3mm rectangular footprint conforms to the EIA/EIAJ standard trimmer layout, making it a drop-in replacement for many common designs.
