Industry's Highest* Rated Power! ROHM Unveils the UCR10C Series of Sintered Metal Shunt Resistors
MWN-AI** Summary
ROHM Semiconductor has officially introduced the UCR10C Series, marking a significant advancement in shunt resistor technology with the highest rated power in the industry for 2012-size configurations (10 m? to 100 m?). This new series is specifically designed to meet the growing demand for high-power handling capabilities in current sensing applications prevalent in automotive and industrial equipment markets.
The UCR10C Series employs a copper-based resistive element formed on an alumina substrate through a sintering process. This innovation enhances heat dissipation, allowing the resistors to achieve rated power levels of 1.0W and 1.25W—effectively doubling the power rating compared to conventional thick film and metal plate resistors of the same size. The increased power capability facilitates component miniaturization, enabling the replacement of larger terminals or wide terminal types while reducing the overall number of components required.
Additionally, the UCR10C Series features a low temperature coefficient of resistance (TCR) ranging from 0 to +60 ppm/°C, which minimizes temperature-induced errors, thus ensuring high-precision current sensing. The resistors have demonstrated robustness comparable to metal plate types under extreme temperature cycling conditions (-55°C to +155°C, 1000 cycles), ensuring reliability in fluctuating environments, especially in automotive applications.
Completely free of lead materials—even in RoHS-exempted areas—this product line underscores ROHM's commitment to reducing environmental impact. The UCR10C Series is now available for purchase online via distributors such as DigiKey, Mouser, and Farnell. Furthermore, ROHM is expanding its portfolio with the upcoming UCR18C Series, a 3216-size (2W) sintered metal shunt resistor, emphasizing its dedication to high power, precision, and reliability in current sensing applications across multiple sectors.
MWN-AI** Analysis
In an increasingly competitive electronics market, ROHM Semiconductor's launch of the UCR10C Series sintered metal shunt resistors positions the company as a leader in high-performance, reliable components essential for automotive and industrial applications.

Santa Clara, CA and Kyoto, Japan, Jan. 22, 2026 (GLOBE NEWSWIRE) -- ROHM today announced it has developed the “UCR10C Series”, which has the industry's highest rated power for 2012-size shunt resistors (10 m? to 100 m?).
Shunt resistors are required to handle higher power for current sensing in both the automotive and industrial equipment markets. Additionally, specific requirements for high junction reliability in these markets has increased annually.
ROHM’s new products form a copper-based resistive element on an alumina substrate via sintering. By optimizing the heat dissipation structure, it achieves rated powers of 1.0W and 1.25W-double that of equivalent-sized products including thick film types and metal plate types. This enables the replacement of products with wide terminal types or larger alternatives, facilitating miniaturization and reducing the number of components required.
Furthermore, the use of a metal resistive element achieves a low TCR (0 to +60 ppm/°C). This minimizes errors due to temperature changes, enabling high-precision current sensing. Moreover, it achieves the same level of durability as the metal plate types in temperature cycle testing (-55°C / +155°C, 1000 cycles). This ensures high bonding reliability even in applications with extreme temperature fluctuations, such as automotive use, enabling stable, long-term operation.
This series is fully lead-free. No lead materials are present, even in RoHS-exempted areas, thus reducing environmental impact.
These products are available for online purchase and can be purchased through online distributors such as DigiKey, Mouser and Farnell.
As part of its future expansion plans, ROHM has also commenced development of the 3216-size (2W) sintered metal shunt resistor, the “UCR18C Series”, further enhancing its product line-up that combines high power, high precision and high reliability.
