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.

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.

•Before using components in circuits where they will be exposed to transients such as pulse loads (short-duration, high-level loads), be certain to evaluate the
component in the mounted state. 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.
