MNR34

Resistors

Compact Chip Resistor Networks MNR34 (3216×4 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 four 3216 chips (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 specifications are subject to change without notice. Carefully check the specification sheet supplied with the product before using or ordering it.

Frequently Asked Questions

How can I ensure proper component reliability during operation?

The component should be evaluated in its mounted state, especially when exposed to transients like pulse loads, and must not operate above its rated voltage.

What is the recommended temperature for soldering this resistor network?

For standard soldering conditions, immerse the components in a bath at 235±5°C for a duration of 2.0±0.5s.

Does this product support high-density mounting?

Yes, it can be mounted even more densely than four 3216 chips (MCR18), which reduces the count and cost of parts and mounting equipment.

What condition must I meet if the ambient temperature exceeds 70°C?

If the ambient temperature exceeds 70°C, the rated power must be derated according to the power derating curve provided in Figure 1.
