mnr04 resistors 1/4 chip resistor networks mnr04 (1005 4 size) ! features 1) extremely small and light area ratio is 60% smaller than that of chip 3216 (mnr14), while weight ratio has been cut 75%. 2) high-density mounting can be mounted even more densely than four 1005 chips (mcr01), and mounting costs are lower. 3) can be mounted on a wide variety of devices squared corners make it excellent for mounting on image recognition devices. 4) convex electrodes easy to check the fillet after soldering is finished. 5) rohm resistors comply with the international standard iso-9001. furthermore, changes to the design and specifications of products may occur without notice. therefore, before ordering or using this product, please make sure to reconfirm the specification sheet before ordering or using this product. ! ! ! ! ratings item conditions specifications 0.063w (1 / 16w) rated power rated voltage operating temperature nominal resistance see table 1. e : voltage rating (v) p : power rating (w) r : nominal resistance ( ? ) limiting element voltage ? 55 c~ + 125 c 25v at 70 c power must be derated according to the power derating curve in figure 1 when ambient temperature exceeds 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 maximum operating voltage. e = p r 0 20 40 60 80 100 e 55 0 70 100 125 ambient temperature ( c) power load (%) fig.1
