DFN www.vishay.com Vishay Dale Thin Film Dual Flat No Lead Molded Precision Thin Film Resistor Surface Mount Network FEATURES 0.8 mm lead pitch MSL level 1 per J-STD-020 Low profile 1 mm seated height Small size 4 mm x 4 mm size 50 % board savings over SOIC packages Wide resistance range 100 to 100 k available Custom configurations available Low TCR 25 ppm, TCR tracking to 3 ppm Ratio tolerances to 0.025 % The DFN series of precision surface mount resistor networks Material categorization: for definitions of compliance feature isolated thin film precision resistors mounted in a please see www.vishay.com/doc 99912 0.8 mm pitch 4 mm x 4 mm dual flat no lead package. The TYPICAL PERFORMANCE networks feature 50 % savings in board space over traditional SOIC packages. They are ideally suited for ABSOLUTE TRACKING applications of unity gain operational amplifiers that require TCR 25 3 close TC tracking and tight ratio tolerances over temperature. Custom configurations are available upon ABSOLUTE RATIO request.
