Vishay Foil Resistors FRSM 303261 Series (EEE 'space qualified')

This FRSM ultra high precision resistor series from Vishay Foil Resistors is tested to EEE-INST-002 and MIL-PRF-55342, specifically for space and military applications. The 303261 series offers a resistance range between 100Ω and 2kΩ, in a small 0603 surface-mount package with wrap-around terminations. These resistors utilise Vishay Foil Resistor'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 +150°C). They have nominal temperature coefficients of resistance of ±0.2ppm/°C typical between -55°C to +125°C (+25°C reference) with tolerances available down to ±0.01% between 250Ω and 2kΩ.
