RS73 – Thick Film Technology with Maximum Precision

The new KOA RS73 series is characterized by high precision and long-term stability. Built using thick film technology, the component enables tolerances as low as 0.1% and a TCR of 25 ppm/K. Tolerances of 0.25% and 0.5%, as well as a TCR of 50 ppm/K, are also offered. The data regarding long-term stability is equally outstanding. In a 1,000h endurance test, the maximum deviation is 0.2%. These are values previously only known from thin film resistors. In this respect, the component can also be considered an alternative to precision thin film resistors.

The component is currently only available in the 0603 package size; sizes 0402, 0805, and 1206 are expected to follow soon. You are welcome to download the product data sheet.

The RS73 series also meets the requirements according to AEC-Q200.
