Bourns TC33 Series Trimmer Potentiometer 50K Ohm Top Adjust Surface Mount

Bourns TC33 Series Trimmer Potentiometer 50K Ohm is a single-turn, top-adjust cermet trimmer in a compact 3.3 mm (W) x 4.3 mm (H) x 1.5 mm (D) surface-mount package, with a 50 kOhm track resistance and a 100 mW power rating.

Overview

The Bourns TC33 Series is a high-precision, 3 mm SMD trimming potentiometer designed for modern electronic assemblies. The Trimpot component is recommended for reflow soldering processes, supporting compatibility with automated production lines. Its rotor design is compatible with both pick-and-place equipment and automatic adjustment systems, which facilitates efficient, high-volume manufacturing. For manual calibration, the trimmer can be adjusted using a standard H-90 tool.

Engineered for critical applications, the trimmer delivers essentially infinite resolution, providing fine-grained control over electrical parameters. It has a continuous mechanical adjustment angle of 200°. The compact 3 mm rectangular footprint conforms to the EIA/EIAJ standard trimmer layout, making it a drop-in replacement for many common designs.
