This document describes the features and characteristics of DSM Vishay Foil Resistors, including high precision, high stability, low temperature coefficient of resistance, and low current noise.
The DSM series is a high‑precision bulk‑metal foil surface‑mount voltage divider offering an absolute temperature coefficient of ±2 ppm/°C and tracking of 0.5 ppm/°C. It provides tight tolerance (±0.02 % absolute, 0.01 % match) and excellent ratio stability (0.005 % over 2000 h at 70 °C). The device integrates a matched pair of resistors in a compact epoxy package with low current noise and high ESD protection.
Typical applications include instrumentation amplifiers, bridge networks, differential amplifiers, medical and test equipment, and military or airborne systems. Custom values and ratios are available, and the part can be ordered using the global part number Y1485V0067BA9W in tape‑and‑reel or waffle‑pack formats.
