Modules and Others
Helping to solve social issues by providing high added value
ROHM’s thermal printheads and resistors are high mar-ket-share products with a global share ranked in the top 5 and we have a lineup of products for customers around the world to choose from. At the same time, we are developing products which contribute to “energy savings” and “miniatur-ization” for customers as stated in our Management Vision, and we are striving to help solve social issues. For example, in printheads, we are mass-producing energy-saving thermal printheads which can reduce the customers’ drive battery from two cells to one. In resistors, we are strengthening our lineup of shunt resistors and other special resistors which support small sizes and high power with the increasing need for high functionality in automobiles. In addition, we are switching our product component materials to general-pur-pose materials that are easier to procure to contribute to energy conservation in society as a whole.

Key products
Resistors
One of the indispensable components in electric circuits, resistors work to ensure smooth operation of electric circuits. They provide high added value because they are high performance, highly reliable, and can be miniaturized.
Print heads
These use ROHM’s proprietary semiconductor, thick-film printing, and thin-film deposition technologies, and are small, save energy, are high quality, and provide high image quality.
Sensor modules
ROHM can propose total solutions by combining the world’s top-level sensor variations with ROHM’s core technologies.

Strengthening the “PSR Series” lineup of metal plate shunt resistors to contribute to the min-iaturization and energy saving of automotive and industrial equipment
In recent years, thin power modules with cooling mechanisms on both sides of the module are increasing in EV traction invert-ers to miniaturize the housing, and there is a growing demand to build shunt resistors into these modules. However, conven-tional products are taller, and there is a risk that they may reduce the cooling efficiency of power devices. In response, ROHM developed the metal plate shunt resistor "PSR350," which has roughly half the height of conventional products in the 12W rated power class. In addition, the Company plans to commercialize the “PSR100” 0.2mΩ product, which is compact and detects even larger currents, and the “PSR330,” which is the industry’s smallest metal plate shunt resistor in the 15W rated power class. Going forward, ROHM will contribute to the miniaturization and energy saving of automotive and industrial equip-ment by strengthening and improving the performance of the “PSR Series” lineup of metal plate shunt resistors.
