RMKMS408-20KBWT Description

The RMKMS408-20KBWT from Vishay is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 4-resistor isolated network features a 20 kΩ resistance value per element with an exceptional ±0.1% tolerance and a low ±10ppm/°C/±15ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Housed in an 8-pin SO (Small Outline) molded package, it offers surface-mount (SMD) compatibility with gull-wing terminations for reliable PCB integration. The device operates over a wide temperature range of -55°C to +125°C, with derated power handling up to 125°C. Its 1/4W total power rating (50mW per resistor) and 50V maximum voltage rating make it suitable for precision analog and digital circuits.
