Precision Resistor Networks
SR02
& S2 Series
Description
The
SR02
& S2 Series resistor networks are precision-class metal film components featuring tight resistance
tolerance and low values of temperature coefficient of resistance (TCR). This resistor network package
provides both excellent resistance ratio and TCR tracking.
