Resistors
Compact Chip Resistor Networks
MNR32
(1206×2 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 two 1206 chips (MCR18). Also, the number of parts and costs of mounting
have been reduced.
4) ROHM resistors have approved ISO9001- / ISO/TS 16949- certification.
Design and specifications are subject to change without notice. Carefully check the specification sheet supplied with
the product before using or ordering it.

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.

•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.
