MNR18
(0603×8 size)
Features
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.

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.
