The FRSM ultra high precision resistor series from VFR offers a resistance range between 5Ω and 8kΩ, all in a small 0805 surface-mount package with wrap-around terminations. These resistors utilise VFR’s newest Z-1 Bulk Metal® foil resistor technology for improved load life stability (up to 25ppm) and higher working temperatures (balanced temperature characteristics over a range from -55°C to more than 175°C). They have nominal temperature coefficients of resistance of ±0.05ppm/°C typical between 0°C to +60°C and ±0.2ppm/°C typical between -55°C to +125°C (+25°C reference) with tolerances available down to ±0.01% between 250Ω and 8kΩ.
