Vishay created precision resistors with 0.05% tolerance and a temperature coefficient of ±2.5ppm/°C. They are in the FRFS0402 Series, based on ‘Z1 Foil’ precision foil resistor elements by Vishay Precision Group. As well as 0.05%, four other tolerance ratings are available: 0.1, 0.25, 0.5 and 1%. Load life stability is typically ±0.01% (70°C, 2000 h, rated power). In ...
