With the MCRx family, ROHM has increased the range of general-purpose chip resistors in its inventory. More miniaturization and improved performance in a range of applications are its intended outcomes. The new lineup includes the high-power MCRS series and low-resistance, high-power MCRL series.
MCRx Family of Compact, High-Performance ResistorsÂ
In today’s era of advancing functionality and electrification, the increased miniaturization and improved performance of electronic components have become critical issues. This is especially evident in the automotive market, where the proliferation of electric vehicles (xEVs) is accelerating the use of 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.
By improving the internal structure and adding new materials, the MCRS series enhances:
- Rated power and TCR (Temperature Coefficient of Resistance) properties,
- Allowing for use in a smaller size than traditional devices.
- Choose the perfect product based on mounting space needs with a wide range of sizes, 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).
- Expands design options and results in a small, effective circuit design.
- The MCRL series, a low-resistance version of the MCRS series, is perfect for current detecting applications and comes in sizes ranging from 0805-size (0.08inch × 0.05inch) / 2012-size (2.0mm × 1.2mm) to 2512-size (0.25inch × 0.12inch) / 6432-size (6.4mm × 3.2mm).
All sizes of the MCRx family benefit from increased production efficiency, quality, and product reliability with a revamped internal structure.
This series, which complies with the AEC-Q200 automotive reliability standard, helps to expand the market for communications infrastructure, including base stations, servers, and industrial automation equipment, while also satisfying the growing need for electric vehicles (xEVs).
Furthermore, the items are intended for consistent, long-term supply, enabling ongoing use in long-lasting applications like industrial machinery.
Compact 0201-size (0.024-inch × 0.012-inch) and 0603-size (0.6mm × 0.3mm) components that can endure temperatures up to +155°C will be added to the MCRS series. Simultaneously, the MCRE series will soon provide products in the 01005 (0.016 inch × 0.008 inch) and 0402 (0.4mm × 0.2mm) sizes that are entirely lead-free.
These changes will help ROHM to respond to the demand for greater downsizing while complying with environmentally-driven voluntary requirements and export limitations.
In the future, ROHM is committed to creating and producing products that meet the various demands of clients across the globe. Specifically, ROHM will keep adding resistors—its original products—to its inventory, which will increase reliability and downsizing while guaranteeing a steady supply over the long run.
ROHM aims to strengthen its position in the market and propel the advancement of electronic components by continuously providing new value through technological innovation.
