VISHAY 43 Series Cermet Trimmer Potentiometer, 50kohm, 18-Turn

The VISHAY 43 Series Multi-Turn Trimmer Potentiometer is a high-precision, through-hole mounted component designed for reliable adjustment in demanding electronic circuits. Featuring a cermet (ceramic-metal) resistive element, it offers excellent stability and a long operational lifespan, making it a trusted choice for calibration and tuning applications where accuracy is paramount.

This trimmer provides a track resistance of 50kohm with a tolerance of ±10%, allowing for fine-grained control over signal levels. Its multi-turn design, offering 18 full rotations of the adjustment screw, enables exceptionally precise resistance settings. This is ideal for applications where a standard single-turn potentiometer would lack the necessary resolution.

Built to robust standards, it has a power rating of 750mW and can operate across a wide temperature range from -55°C to 125°C. It conforms to the MIL-R-22097 qualification, indicating its suitability for rigorous and high-reliability environments. The component features a side-adjustment type and is housed in a standard 3/4 inch rectangular package, ensuring compatibility with common PCB layouts and facilitating easy installation and adjustment.
