Dual Flat No Lead Molded Precision Thin Film Resistor

Surface Mount Network

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

tolerances

over

temperature. Custom configurations are available upon

request.
