ROHM Expands High-Accuracy EROM Models for Shunt Resistors

Executive Summary

• ROHM Semiconductor announced an expanded lineup of its EROM (Embeddable BCI‑ROM) shunt resistor models, adding the new PMR series to the existing PSR series.
• The new EROM models are now standard in Siemens’ Simcenter™ Flotherm™ thermal design software (version 2510 and later), facilitating more accurate thermal simulations for automotive and industrial applications.
• ROHM highlighted the high‑accuracy performance of the models (±5 % measurement deviation for surface temperature and thermal resistance) and reiterated its commitment to supporting customers’ design and development activities.

Key Details

• New Models Added: PMR series added to the EROM shunt resistor portfolio; PSR series remains available.
• Performance Specs: Measurement deviation within ±5 % for both surface temperature (ΔT) and thermal resistance, enabling precise thermal analysis.
• Software Integration: EROM models are now a standard component in Siemens’ Simcenter™ Flotherm™ 2510+ software, improving simulation accuracy and data confidentiality for component manufacturers.
• Target Applications: Automotive and industrial equipment where high‑accuracy current detection and reliability are critical.
• Availability: Models are now listed on ROHM’s website and can be accessed through the Simcenter™ Flotherm™ platform.
