ROHM Semiconductor has announced an expanded selection of its EROM (Embeddable BCI-ROM) thermal simulation models for shunt resistors, now accessible on ROHM’s website and included as standard in Siemens’ Simcenter Flotherm electronic thermal design software (version 2510 and later). Shunt resistor models serve critical roles in automotive and industrial equipment, supporting high-accuracy current detection and operational reliability.

The EROM simulation lineup now includes the PMR series, in addition to the existing PSR series. ROHM reports that EROM models deliver high simulation fidelity, with measurement deviation within plus or minus 5 percent for both surface temperature (delta T) and thermal resistance. This increased accuracy is designed to enable thermal analysis closely matching real-world conditions, which the company claims will improve simulation reliability at the design stage and enhance development efficiency for engineers.

ROHM says that integrating EROM models as a standard feature within Simcenter Flotherm allows component and systems manufacturers to share precise thermal analysis data more efficiently, while maintaining the confidentiality of sensitive design information.
