Recommended IR – Reflow Profile
(Solder: Sn96.5 / Ag3 / Cu0.5)
Peak: 250 +5 / -0 °C, 5 seconds

Soldering Zone: 230 °C or higher, 30 ± 10 seconds
High Power Chip Resistors and Thermal Management
Stackpole has developed several surface mount resistor series in addition to our current sense resistors, which have had higher power
ratings than standard resistor chips. 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°C for the CSS / CSSH series and 70°C for all other high power resistor series. In addition, IPC and
UL best practices dictate that the combined temperature on any resistor due to power dissipated and ambient air shall be no more than
105°C. At first glance this wouldn’t seem too difficult, however the graph below shows typical heat rise for the CSR ½ 100 milliohms
at full rated power. The heat rise for the RMCP and RNCP would be similar. The RHC with its unique materials, design, and processes
would have less heat rise and therefore would be easier to implement for any given customer.
