Expanded high-accuracy models for shunt resistors

ROHM has expanded its lineup of EROM (Embeddable BCI-ROM) models for shunt resistors and offers them on its website. These models are also now standard in Siemens' electronic thermal design software, Simcenter Flotherm.

The company's shunt resistors are widely used in automotive and industrial equipment applications, where their high-accuracy current detection and superior reliability are highly valued. It has added the PMR series to the EROM lineup, alongside the previously available PSR series.

The EROM models attain high accuracy with a measurement deviation within ±5% for surface temperature (Delta T) and thermal resistance, allowing thermal analysis that closely reflects actual operating conditions. This contributes to improved simulation accuracy in the thermal design phase and improves overall development efficiency.

Also, by standard implementation in Simcenter Flotherm, these models make it more straightforward for component manufacturers and set manufacturers to share thermal analysis data. This provides for highly accurate and efficient simulations while maintaining the confidentiality of proprietary information.

Going forward, the company will continue to improve the support for customers' design and development activities through its high-performance components and advanced simulation models.
