to 100 kΩ available
Custom configurations available
Low TCR ± 25 ppm, TCR tracking to ± 3 ppm
Ratio tolerances to ± 0.025 %
Compliant to RoHS directive 2002/95/EC
The DFN series of precision surface mount resistor networks
feature isolated thin film precision resistors mounted in a
0.8 mm pitch 4 mm x 4 mm dual flat no lead package. The
networks feature 50 % savings in board space over
traditional SOIC packages. They are ideally suited for
applications of unity gain operational amplifiers that require
close TC tracking and tight ratio tolerances over
temperature. Custom configurations are available upon
request.
