Santa Clara, CA and Kyoto, Japan, May 04, 2021 (GLOBE NEWSWIRE) — ROHM Semiconductor at this time introduced the event of the GMR320 collection of shunt resistors that includes a rated energy of 10W, the most important within the high-power, low-ohmic GMR lineup designed for high-power purposes within the automotive, industrial gear, and residential equipment sectors.
Recent years have seen an growing demand within the automotive and industrial fields for increased energy purposes that eat much less energy. This in flip requires shunt resistors that assist excessive accuracy present detection to realize energy-efficient drive in a range of purposes. ROHM’s GMR collection of shunt resistors allows excessive accuracy driving even at excessive energy, making them excellent for purposes within the automotive, industrial and client sectors.
The newly developed GMR320 collection is obtainable in a resistance vary from 5mΩ to 100mΩ and a rated energy of 10W, making them excellent for car ECUs and headlamps, in addition to motors and energy provides for industrial gear and residential home equipment. Unique supplies and construction enable ROHM to scale back floor temperature rise by 23% over normal merchandise, making certain excessive sturdiness in opposition to overcurrent hundreds, whereas superior warmth dissipation makes it doable to realize steady efficiency and the smallest dimension (7.1mm x 4.2mm) within the 10W class with out a change in resistance worth even at overcurrent hundreds.
At the identical time, adopting a high-performance metallic alloy because the resistive component supplies a superior TCR of ±25ppm/°C or much less – even within the low resistance area – enabling dependable, excessive accuracy present detection. The collection is certified beneath the AEC-Q200 automotive reliability normal for passive parts, making certain a most working temperature of 170°C that gives excessive reliability even in car environments the place temperatures will be notably extreme, corresponding to within the engine compartment.
Thermal simulation fashions for shunt resistors (together with the brand new merchandise) will even be out there on ROHM’s web site from October 2021, permitting customers to carry out simulations earlier than designing the precise machine (even in high-power purposes the place thermal design is especially tough), significantly lowering design manhours.
