ROHM Co., Ltd. has launched the SDR01 Series of excessive anti-surge chip resistors. These resistors obtain a rated energy of 0.33 watts inside the compact 0402 (1005 Metric) dimension, optimizing them to be used in high-density digital tools purposes.
The new SDR01 Series is tailor-made for automotive, industrial, shopper electronics, and AI server purposes, the place mounting densities are on the rise. The sequence permits the alternative of larger-size resistors and consolidation of a number of resistors, thus saving board area and lowering element rely whereas sustaining the reliability required for such parts.
As calls for for extra useful and high-power digital tools develop, the necessity for compact and dependable parts, similar to anti-surge chip resistors, additionally will increase. These parts are essential for energy provide circuits and interfaces, the place resistance to surges, electrostatic discharge (ESD), and high-power functionality are important.
To deal with these necessities, ROHM has enhanced the resistive aspect and electrode designs of the SDR01 Series. This enchancment ensures that the excessive rated energy is maintained within the compact 0402 dimension whereas guaranteeing the reliability anticipated of excessive anti-surge chip resistors.
The SDR01 Series ensures 0.33 watts as much as a rated terminal temperature of 125 levels Celsius, making them splendid for demanding thermal environments. These environments embrace areas with high-density mounting and proximity to heat-generating parts, successfully lowering the thermal design burden in these eventualities.
Additionally, these merchandise obtain a temperature coefficient of resistance (TCR) of plus or minus 100 ppm per diploma Celsius for resistances between 10 ohms and a couple of.2 megohms. By minimizing resistance-value fluctuations as a consequence of temperature adjustments, the SDR01 Series helps steady circuit operation, contributing to the event of smaller, extra dependable energy provide circuits and peripheral interface circuits.
ROHM continues to increase its lineup of high-reliability chip resistors, aiming to advance miniaturization, improve energy dealing with, and improve reliability in digital tools by constructing on the improvements introduced within the SDR01 Series.
