UPR high-precision resistor series, is produced by our company EE1/10 finished high-precision metal film resistors, assembled by matching. EE Series resistors with high stability / precision / low temperature coefficient of the technical characteristics, to meet the EE series resistance quality consistency test project requirements. Features: Matching compensation effect because, as a whole has a smaller nominal resistance value and temperature coefficient of error for precision electronic instrumentation for analog electronic circuits.。
