Product Overview
The RS73 High Reliability Chip Resistors are metal-glaze thick film resistors designed for surface mounting. They offer high precision with T.C.R. down to 2510-6/K and tolerances as tight as 0.1%. These resistors provide high reliability with low R values in reliability testing and are suitable for both flow and reflow solderings. Products with lead-free termination meet EU-RoHS requirements and are AEC-Q200 tested.

Note:
1 Measurement Temperature: +25/+125. Cold T.C.R. (55/+25) is 50+2510-6/K.
Rated voltage = Power RatingResistance value or Max. working voltage, whichever is lower.
For resistors operated at an ambient temperature of 85 or higher, power shall be derated according to the derating curve.
If any questions arise whether to use the "Rated Ambient Temperature" or the "Rated Terminal Part Temperature" in your usage conditions, give priority to the "Rated Terminal Part Temperature".
