2.0 Mechanical
Precision Resistor Network
BR Series
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.
Specification subject to change - Please call factory.
Note 1: Ratio values greater than 50:1 only available in ±5 ppm/°C TCR tracking tolerance
Note 2: ±1ppm/°C TCR Tracking only available for identical resistance values.
