KOA Corporation RS73 Series High Reliability Resistors
KOA Corporation RS73 Series High Precision and High-Reliability Chip Resistors are ESD transient-tolerant metal-glaze devices that use thick film technology. These devices are ideal for applications requiring high precision, low T.C.R., efficient long-term stability, and high ESD capabilities. The RS73 series combines the accuracy of thin film resistors with the ruggedness of thick film resistors. These components feature a high power rating per size and high short-time overload performance. These resistors offer efficient long-term stability of ±0.2% and are available in 0402, 0603, 0805, and 1206-inch sizes. The RS73 series resistors have a T.C.R. of ±25ppm/K and a low tolerance of ±0.1%, ideal for precision designs in high-accuracy sensing or voltage detection circuits in automotive, industrial, and measuring applications.
