rev date: 11/05/2012 6 www.seielect.com this specification may be changed at any time witho ut prior notice marketing@seielect.com please confirm technical specifications before you order and/or use. csr/csrn series thick film current sensing resistor stackpole electronics, inc. resistive product solutions high power chip resistors and thermal management stackpole has developed several surface mount resistor se ries in addition to our current sense resistors, which have had higher power ratings than standard resist or chips. this has caused some uncertainty and even confusion by users as to how to reliably use these resi stors at the higher power ratings in their designs. the data sheets for the rhc, rmcp, rncp, csr, csrn, c srf, 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. in addition, ipc and ul best practices dictate that the combined temperature on any resistor due to power dissipa ted and ambient air shall be no more than 105c. at first glance this wouldn?t seem too difficult, howe ver the graph below shows typical heat rise for the csr ? 100 milliohm at full rated power. the heat rise f or the rmcp and rncp would be similar. the rhc with its unique materials, design, and processes would have le ss heat rise and therefore would be easier to implement for any given customer. the 102 degrees c heat rise shown here would indicate there will be additional thermal reduction techniques needed to keep this part under 105c total hot spot t emperature if this part is to be used at 0.75 watts o f power. however, this same part at the usual power ra ting for this size would have a heat rise of around 72 degrees c. this additional heat rise may be dealt wi th using wider conductor traces, larger solder pads and land patterns under the solder mask, heavier copper in t he conductors, vias through pcb, air movement, and heat sinks, among many other techniques. because of the v ariety of methods customers can use to lower the effective heat rise of the circuit, resistor manufact urers simply specify power ratings with the limitations on ambient air temperature and total hot spot temper atures and leave the details of how to best accomplish this to the design engineers. design guidelines for pro ducts in various market segments can vary widely so it would be unnecessarily constraining for a resistor man ufacturer to recommend the use of any of these methods over another. note: the final resistance value can be affected by the board layout and assembly process, especially the si ze of the mounting pads and the amount of solder used. this is especially notable for resistance values 50 m . this should be taken into account when designing.
