TaNFilm® Flat Precision Resistor Array Welwyn Components SON Series • Compatible with standard SOIC footprint (210 Series) • Superior temperature performance • Tested for COTS Applications • Absolute tolerances to ±0.05% • Ratio tolerances to ±0.01% Welwyn’s TaNFilm® Small Outline Leadless Resistor Networks are ideally suited for applications requiring precision, long term reliability and stability in a small area. Its monolithic construction eliminates vulnerable terminations such as solder connections. The SON package is ideal for the all surface mount production reflow techniques while still possessing all the unique qualities of our TaNFilm® thin film system. Testing has demonstrated performance exceeding MIL-PRF-83401 Characteristic H.
