EROM Models Bring High-Accuracy Thermal Analysis to Shunt Resistors
ROHM Semiconductor further expanded the lineup of its EROM (Embeddable BCI-ROM) models for shunt resistors. Due to their popularity in automotive and industrial equipment applications, the company added the PMR series to the EROM lineup, alongside the previously available PSR series. In addition, they’re now included in the component library of Siemens’ Simcenter Flotherm, electronic thermal design software.
The EROM models achieve high accuracy with a measurement deviation within ±5% for both surface temperature (ΔT) and thermal resistance, enabling thermal analysis that closely reflects actual operating conditions. This contributes to improved simulation accuracy in the thermal design phase and enhances overall development efficiency.
Their inclusion in Siemens’ Simcenter Flotherm make it easier for component manufacturers and set manufacturers to share thermal-analysis data. It ultimately leads to highly accurate and efficient simulations while maintaining the confidentiality of proprietary information.

Lee Goldberg is a self-identified “Recovering Engineer,” Maker/Hacker, Green-Tech Maven, Aviator, Gadfly, and Geek Dad. He spent the first 18 years of his career helping design microprocessors, embedded systems, renewable energy applications, and the occasional interplanetary spacecraft. After trading his ‘scope and soldering iron for a keyboard and a second career as a tech journalist, he’s spent the next two decades at several print and online engineering publications.
Lee’s current focus is power electronics, especially the technologies involved with energy efficiency, energy management, and renewable energy. This dovetails with his coverage of sustainable technologies and various environmental and social issues within the engineering community that he began in 1996. Lee also covers 3D printers, open-source hardware, and other Maker/Hacker technologies.
Lee holds a BSEE in Electrical Engineering from Thomas Edison College, and participated in a colloquium on technology, society, and the environment at Goddard College’s Institute for Social Ecology. His book, “Green Electronics/Green Bottom Line - A Commonsense Guide To Environmentally Responsible Engineering and Management,” was published by Newnes Press.
Lee, his wife Catherine, and his daughter Anwyn currently reside in the outskirts of Princeton N.J., where they masquerade as a typical suburban family.
