MNR34 Resistors Chip resistor networks MNR34 (32164 size) Features 1) Convex electrodes Easy to check the fillet after soldering is finished. 2) Compatible with a wide range of mounting equipment. Squared corners make it excellent for mounting using image recognition devices. 3) High-density mounting Can be mounted even more densely than four 3216 chips (MCR18). Also, the number of parts and cost of mounting have been reduced. 4) ROHM resistors have approved ISO-9001 certification. Design and specifications are subject to change without notice. Carefully check the specification sheet supplied with the product before using or ordering it. Ratings Item Conditions Specifications 0.125W (1 / 8W) Rated power Power must be derated according to the power derating curve in at 70C Figure 1 when ambient temperature exceeds 70C. 100 80 60 40 20 0 55 0 70 100 125 AMBIENT TEMPERATURE (C) Fig.1 Rated voltage 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.
