RS73 High Reliability Chip Resistors
The RS73 series are high reliability chip resistors designed for surface mounting. These metal-glaze thick film resistors offer high precision with T.C.R. of 25x10-6/K and tolerances as tight as 0.1%. They are suitable for both flow and reflow solderings and meet EU RoHS requirements for lead-free terminations. Tested to AEC-Q200 standards, these resistors are ideal for applications requiring high precision and reliability, with specific performance characteristics detailed in the reliability tests.

*1 Measurement Temperature: +25C/+125C. Cold T.C.R. (-55C/+25C) is -50~+25x10-6/K
*2 Please inquire about E-192
Derating Curve Note: For resistors operated at an ambient temperature of 85C or above, or at a terminal part temperature as described for each size or above, power rating shall be derated in accordance with the derating curve. Priority should be given to the "Rated Terminal Part Temperature" if there are any questions about which derating curve to use.
