Resistors
Compact Chip Resistor Networks
MNR34 (3216×4 size)
zFeatures
1) Convex electrodes
Easy to check the fillet after soldering is finished.
2) Compatible with a wide range of moun ting equipmen t.
Squared corners make it excellent for mounting using image recognition devices.
3) High-density mounting
Can be mounted even more d ens el y t ha n f our 32 1 6 chi ps (MCR18). Also, the number of parts and cost of mounting
have been reduced.
4) ROHM resistors have approved ISO9001- / ISO/TS 16949- certification.
Design and specificatio ns are subj ect to change wit hout not ice. Carefull y check the s pecification sheet suppli ed with
the product before using or ordering it.

Operating temperature
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 lo ads), 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 st ate voltage that
is greater than its rated voltage.
