ROHM's SDR01 Chip Resistors Hit 0.33W in 0402 Size
Kyoto – September 16, 2026 -- ROHM Co., Ltd. has developed the SDR01 Series of high anti-surge chip resistors, achieving a rated power of 0.33W in the compact 0402 (1005 Metric) size, enabling manufacturers to replace larger-size resistors while maintaining the reliability standards required for anti-surge components.
New Resistors Guarantee 0.33W Up to 125 Degrees Celsius
The SDR01 Series guarantees 0.33W of rated power up to a terminal temperature of Tk=125 deg C, easing thermal design constraints in high-density mounting environments and areas near heat-generating components. ROHM achieved this by optimizing the resistive element and electrode designs of the chip, allowing high power handling to be certified in a smaller footprint without compromising the durability expected of anti-surge products.
