ROHM Semiconductor has expanded its lineup of EROM (Embeddable BCI-ROM) models for shunt resistors, now available on ROHM’s website and included as standard models in Siemens’ electronic thermal design software, Simcenter Flotherm.
ROHM’s shunt resistors are used across automotive systems, including electric vehicles (EVs), where accurate current sensing is required in battery management systems, onboard chargers, dc-dc converters, traction inverters, and power-distribution modules.
They can also be used in industrial equipment and other high-reliability power platforms. The PMR series has now been added to the EROM lineup alongside the existing PSR series.
The EROM models achieve a measurement deviation within ±5% for surface temperature (ΔT) and thermal resistance, allowing thermal simulations that more closely reflect real operating conditions. This improves accuracy during the design phase and supports more efficient development of thermally constrained systems such as EV power electronics.
With their inclusion in Simcenter Flotherm, the models allow component and system manufacturers to exchange thermal analysis data more easily while maintaining confidentiality of proprietary information. This supports consistent simulation workflows for automotive, EV, and industrial applications.
ROHM plans to continue expanding its simulation support alongside its component portfolio.
