ROHM shunt resistors were developed using metallic material processing technology cultivated over many years to ensure compatibility with a wide range of applications, from portable devices such as smartphones to automotive and industrial systems requiring a greater degree of reliability. This allowed ROHM to adopt a special high performance alloy for the resistive element, enabling high accuracy current detection with excellent temperature characteristics.
GMR Series (Under Development)
The GMR series of high power shunt resistors are characterized by high heat dissipation and superior reliability. Optimizing the heat dissipation pathway makes it possible to ensure higher rated power in a compact form factor.
The PMR series of ultra-low-ohmic shunt resistors are available from 1mΩ. The proprietary trim-less structure prevents heat concentration, reducing temperature rise, while low inductance makes high accuracy current detection possible. The lineup includes a broad range of sizes to suit a variety of applications.
◆A special alloy utilized for the resistive element makes it possible to provide stable ultra-low resistances
◆Original trimless structure minimizes temperature rise
The PML series of metal plate type ultra-low-ohmic chip resistors features a wide terminal design that improves heat dissipation and reliability, making them ideal for large current high-speed switching circuits.
