MNR02 resistors chip resistor networks MNR02 (1005 2 size) ! features 1) extremely small and light area ratio is 60% smaller than that of chip 1616 (mnr12), while weight ratio has been cut 75%. 2) high-density mounting can be mounted even more densely than two 1005 chips (mcr01). also, the cost of mounting has been reduced. 3) compatible with a wide range of mounting equipment. squared corners make it excellent for mounting using image recognition devices. 4) convex electrodes easy to check the fillet after soldering is finished. 5) rohm resistors have obtained iso-9001 certification. design and specifications are subject to change without notice. carefully check the specification sheet before using or ordering it. ! ! ! ! ratings item conditions specifications 0.063w (1 / 16w) rated power rated voltage operating temperature nominal resistance see table 1. limiting element voltage ? 55 c to + 125 c 25v at 70 c the voltage rating is calculated by the following equation. if the value obtained exceeds the limiting element voltage, the voltage rating is equal to the maximum operating voltage. e: rated voltage (v) p: rated power (w) r: nominal resistance ( ? ) e = p r power must be derated according to the power derating curve in figure 1 when ambient temperature exceeds 70 c. 0 20 40 60 80 100 ? 55 0 70 100 125 155 ambient temperature ( c) power load (%) fig.1
