World First! Realized 0.2 kW Rated Power in a 1005 Size Chip
ROHM Developed the “ESR01” Series of Anti-Surge Chip Resistors

In recent years, as electronic devices in general have become smaller and more sophisticated, there has been growing demand for compact, high-power resistors. Using ROHM’s high-precision processing, printing, and trimming technologies acquired from the development of ultra-compact chip resistors (0402 size), the company has now developed anti-surge chip resistors that achieve a high power of 0.2W in the 1005 size for the first time in the world. Compared to the ROHM’s conventional products (0.063W) of the same size, the “ESR01” series of anti-surge chip resistors provides about 3.2 times more rated power and makes it possible to substantially reduce the mounting area (by about 60%).
