Precision Resistor Networks
SR02 & S2 Series
Descri
p
tion
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.
