Precision Resistor Network
BR Series
Specification subject to change - Please call factory.
1.0 Description
The BR 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 BGA terminations.
