Overview: Ultra-Low Ohmic High Power Flat Chip Type Shunt Resistors
The PMR100HZP7 is a high-power 6432-size (6.4mm × 3.2mm) model within the PMR series – part of ROHM’s standard metal plateshunt resistor lineup. Features such as a compact size, ultra-low resistance, and high-power capability make it possible to meet theneed for greater miniaturization of large current detection circuits in automotive and industrial equipment applications.

Features・ Achieves a rated power of 5W and rated terminal temperature of 130°C (0.5/1mΩ models)

Flat chip type with protective film achieves class-leading* rated power in the 6432 size, contributing to application miniaturization

・ Proprietary trimming-less structure ensures a distance of 1.6mm (Typ) or more between electrodes
Facilitates current detection wiring and pattern design* ROHM March 2024 study
