Precision Resistor
SR Series
1.0 Description
The SR 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 with wrap around terminations.
