The MU ultra-precision resistor 1-2-3 network series from Alpha Electronics offers a 3 terminal, 2 element resistor network in a small surface-mount package. Each resistive element can range from 10Ω up to 20kΩ all with tight tolerances down to +0.02% absolute and +0.01% matching (1kΩ to 20kΩ). By utilising Alpha's Bulk Metal® foil resistor technology, they are able to produce this resistor network series with low temperature coefficients (both absolute and tracking) as well as excellent long-term stability. The Alpha MU series J-lead terminals provide flexibility once the parts are soldered to the board compared to standard fixed surface-mount resistors.
