MNR34J5ABJ430

MNR34J5ABJ430 Description

The MNR34J5ABJ430 from ROHM Semiconductor is a high-performance 4-resistor array designed for precision surface-mount applications. This component belongs to the MNR series and features a compact 2012 (0805 metric) convex long-side terminal package, measuring 0.205" x 0.122" (5.20mm x 3.10mm) with a low-profile height of 0.026" (0.65mm). Each resistor in the array offers a 43Ω resistance with a ±5% tolerance and a ±200ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. The isolated circuit configuration allows for independent resistor operation, making it ideal for complex PCB designs requiring multiple discrete resistors in a single footprint.
