Santa Clara, CA and Kyoto, Japan, Nov. 30, 2021 (GLOBE NEWSWIRE) — ROHM Semiconductor as we speak launched their new thick-film shunt resistors, LTR100L, optimized for industrial and client purposes. Often used to detect present in battery safety and motor drive circuits, shunt resistors require larger accuracy to enhance reliability and guarantee excessive effectivity operation.
Recent years have seen an emphasis on vitality financial savings within the industrial and client fields, with efforts being made to cut back energy consumption throughout drive operation by utilizing motor inverters. At the identical time, safety circuits have gotten extra vital in these fields as purposes proceed to extend in energy.
ROHM has been engaged on increasing its appreciable lineup, most not too long ago with the GMR320 sequence of metallic plate shunt resistors, launched in February 2021. The units function a better assured rated energy of as much as 10W. Since April 2018, ROHM has been producing the LTR50 sequence of low ohmic thick-film shunt resistors rated at 2W. With these newest merchandise, ROHM has expanded its lineup of thick-film shunt resistors to help a fair larger energy space.
The LTR100L sequence achieves the trade’s highest rated energy of 4W within the 3264 dimension (3.2mm × 6.4mm) / 1225 dimension (0.12inch × 0.25inch) by revising resistor supplies and making use of terminal temperature derating. This makes them splendid for present detection in motor management and overcurrent safety circuits for industrial and client purposes, that are progressing in the direction of larger energy. In addition, optimization of the ingredient construction delivers best-in-class TCR (temperature coefficient of resistance) traits amongst thick-film shunt resistors. As a end result, they aren’t simply affected by temperature – enabling excessive accuracy, excessive reliability present detection.
Samples might be bought from one piece from on-line distributors Digi-Key, Mouser, and Farnell (beginning with 10mΩ, 47mΩ, and 91mΩ). Furthermore, a wide range of content material and instruments helpful for design, similar to utility notes, can be found on ROHM’s web site. Simulation Models will even be launched.
Going ahead, ROHM will proceed to increase its resistor (a founding product) lineup from low to excessive energy. The core goals: attaining larger vitality financial savings and reliability, whereas contributing to the evolution of commercial and client tools by leveraging its strengths as a complete semiconductor producer – to offer resolution proposals using ICs and discrete merchandise.
Thick-Film Shunt Resistors: LTR Series Lineup
The LTR100L sequence makes use of a thick-film construction that makes it comparatively straightforward to increase the resistance worth vary. Please see the Product Lineup desk for an inventory of LTR Series thick-film shunt resistors provided by ROHM.
LTR100L Application Examples
- Industrial tools (manufacturing facility automation, motor peripheral circuits, energy provides)
- Consumer home equipment (air conditioners, washers, fridges, vacuum cleaners)
- Other (two-wheel car headlamps, EV scooters (e-bikes), and so on.)
