ROHM’s new general-purpose chip resistors enable greater miniaturization by delivering equivalent rated power in a smaller size, ensuring a stable long-term supply.
ROHM has expanded its portfolio of general-purpose chip resistors with the MCRx family. Designed to achieve greater miniaturization and enhanced performance across various applications, the new lineup includes the high-power MCRS series and the low-resistance, high-power MCRL series.
In today’s era of advancing functionality and electrification, the increased miniaturization and improved performance of electronic components have become critical issues. This is particularly evident in the automotive market, where the proliferation of electric vehicles (xEVs) is accelerating the demand for electronic components. Similarly, the industrial equipment market is experiencing growing demand for compact, high-performance electronic components as machinery becomes more functional and efficient. ROHM addresses both of these needs with the MCRx family of compact, high-performance resistors.
The MCRS series enhances rated power and TCR (Temperature Coefficient of Resistance) characteristics by optimizing the internal structure and incorporating new materials. This allows for smaller size compared to conventional products. A wide range of sizes is available, from 0402-size (0.04inch × 0.02inch) / 1005-size (1.0mm × 0.5mm) to 2512-size (0.25inch × 0.12inch) / 6432-size (6.4mm × 3.2mm), catering to various mounting space requirements. This leads to compact and efficient circuit designs, significantly enhancing design flexibility.
The MCRL series, a low-resistance variant of the MCRS series, is also available in the same range of sizes, ideal for current detection applications.
The MCRx family of products undergoes a redesigned internal structure, enhancing production efficiency, quality, and product reliability across various sizes. Adhering to the stringent AEC-Q200 automotive reliability standard, this series meets the growing demand for electric vehicles (xEVs) while also contributing to market expansion in communications infrastructure, such as base stations and servers, as well as factory automation equipment. Moreover, these products are designed for long-term stable supply, ensuring continuous use in long-life applications like industrial equipment.
The MCRS series will soon expand to include compact 0201-size (0.024inch × 0.012inch) and 0603-size (0.6mm × 0.3mm) products, capable of withstanding temperatures up to +155°C. Simultaneously, the MCRE series will soon offer completely lead-free 01005-size (0.016inch × 0.008inch) and 0402-size (0.4mm × 0.2mm) products. These additions will enable ROHM to meet the growing demand for further miniaturization while simultaneously complying with environmentally-driven voluntary regulations and export restrictions.
