SOIC resistor networks are the perfect solution for high vol - ume applications that demand a small wiring board footprint. the .050 lead spacing provides higher lead density, increased component count, lower resistor cost, and high reliability. the tantalum nitride flm system on silicon provides precision tolerance, exceptional tcr tracking, low cost and miniature package. excellent performance in harsh, humid environments is a trademark of ircs self-pas - sivating tansil ? resistor flm. the SOIC series is ideally suited for the latest surface mount assembly techniques and each lead can be 100% visually inspected. the compliant gull wing leads relieve thermal expansion and contraction stresses created by soldering and temperature excursions. for applications requiring high performance resistor networks in a low cost, surface mount package, specify irc SOIC resistor networks. electrical data environmental data resistance range 10 - 250k w absolute tolerance to 0.1% ratio tolerance to r1 to 0.05% absolute tcr to 25ppm/c tracking tcr to 5ppm/c element power rating @ 70c isolated schematic bussed schematic 100mw 50mw power rating @ 70c SOIC-n package 8-pin 400mw 14-pin 700mw 16-pin 800mw power rating @ 70c SOIC-w package 16-pin 1.2w 20-pin 1.5w rated operating voltage (not to exceed power x resistance) 100 volts operating temperature -55c to 125c noise <-30db test per mil-prf-83401 typical delta r max delta r thermal shock 0.02% 0.1% power conditioning 0.03% 0.1% high temperature exposure 0.03% 0.05% short-time overload 0.02% 0.05% low temperature storage 0.03% 0.05% life 0.05% 0.1%
