MNR18 Resistors Chip resistor networks MNR18 (0603×8 size) zFeatures 1) Suitable for damping resistors. 2) Convex electrodes Easy to check the fillet after soldering is finished. 3) High-density mounting Can be mounted even densely than eight 0402 chips (MCR01), and mounting costs are lower. 4) Compatible with a wide range of mounting machines. Squared corners make it excellent for mounting using image recognition machines. 5) 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. zRatings Item Conditions Rated power Specifications 0.063W (1 / 16W) Power must be derated according to the power derating curve in Figure 1 when ambient temperature exceeds 70°C. at 70°C POWER LOAD (%) 100 80 60 40 Power for a Packaging Max 0.25W (1 / 4W) 20 0 −55 0 70 100 125 AMBIENT TEMPERATURE (°C) Fig.1 The voltage rating is calculated by the following equation.

In addition, the reliability and performance of this component cannot be guaranteed if it is used with a steady state voltage that is greater than its rated voltage.
