A lineup of high-reliability thick-film chip resistors ranging from 1608 to 3216.

KOA has expanded its lineup of high-reliability thick-film chip resistors with the "RS73 Series." While the 1608 size (rated power 0.2W) has already been released, the 2012 size (rated power 0.25W) and 3216 size (rated power 0.33W) have been added to accommodate a wide range of applications. These are ultra-high precision metal glaze thick-film chip resistors with a resistance tolerance of ±0.1% and a temperature coefficient of resistance (T.C.R.) of ±25×10^-6/K. They are high-reliability products with excellent long-term stability, showing a resistance change rate of ±0.2% or less in reliability tests. At the same time, the sulfur-resistant version RS73-RT has also been added to the lineup.
Examples of applications: Use in high-precision applications such as automotive, industrial machinery, and industrial measurement, and can replace metal film (thin film) chip resistors.
