... This has caused some uncertainty and even confusion by users as to how to reliably use these resistors at the higher power ratings in their designs. The data sheets for the RHC, RMCP, RNCP, CSR, CSRN, CSRF, CSS, and CSSH state that the rated power assumes an ambient temperature of no more than 100 degrees C for the CSS / CSSH series and 70 degrees C for all other high power resistor series ...
