VISHAY 149 Series 1W Cermet Potentiometer, 1K Ohm

The VISHAY 149 Series 1W Cermet Potentiometer is a robust single-gang, switched potentiometer with a track resistance of 1K ohm and a linear taper. Designed for precision and durability, this component features a cermet element with a low temperature coefficient of ±150 ppm/°C, ensuring stable performance across a wide operating temperature range from -40°C to +125°C.

With a rotational life of 50,000 cycles, this potentiometer is built for long-term reliability in demanding applications. Its robust construction and IP 64 sealing level, combined with an RSID switch, make it suitable for environments where dust and moisture protection are required. The component is tested according to CECC 41000 or IEC 60393-1 standards, guaranteeing consistent quality.

This model supports up to three sections PC support plates and comes with PC pin terminals for secure soldering. The adjustment is via a screwdriver slot, allowing precise setting. The multiple module configuration (2 modules) offers flexibility in complex circuits.
