[sense(+) ? sense( - )] 10% of v o,nom . the voltage between the vo(+) and vo( - ) terminal s must not exceed the minimum output overvoltage shut - down value indicated in the feature specifications table. this limit includes any increase in voltage due to remote - sense compensation and output voltage set - point adjustment (trim). see figure 47. if not using the remote - sense feature to regulate the output at the point of load, then connect sense(+) to vo(+) and sense( - ) to vo(- ) at the module. although the output voltage can be increased by both the remote sense and by the trim, the maximum increase for the output voltage is not the sum of both. the maximum increase is the larger of either the remote sense or the trim. the amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. when u sing remote sense and trim: the output voltage of the module can be increased, which at the same output current would increase the power output of the module. care should be taken to ensure that the maximum output power of the module remains at or below th e maximum rated power.

(heatplate) option: to meet basic insulat ion in the end product 1) between the input and output of the module, or 2) between the input and the earth ground, a series capacitor (capable of withstanding 1500v dc) needs to inserted between the case pin and the end termination point, if the case pin is connected to the input or the output of the jrw module or to earth ground. for additional layout guide - lines, refer to fltr100v10 data sheet. post solder cleaning and drying considerations post solder cleaning is usually the final circuit - board assemb ly process prior to electrical board testing. the result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit - board assembly. for guidance on appropriate soldering, cleaning and dry ing procedures, refer to lineage power board mounted power modules: soldering and cleaning application note (ap01 - 056eps). through - hole lead - free soldering information the rohs - compliant through- hole products use the sac (sn/ag/cu) pb - free solder and rohs - compliant components. they are designed to be processed through single or dual wave soldering machines. the pins have an rohs - compliant finish that is compatible with both pb and pb - free wave soldering processes. a maximum preheat rate of 3 c/s is sugge sted. the wave preheat process should be such that the temperature of the power module board is kept below 210 c. for pb solder, the recommended pot temperature is 260 c, while the pb- free solder pot is 270 c max. not all rohs - compliant through - hole pro ducts can be processed with paste - through- hole pb or pb - free reflow process. if additional information is needed, please consult with your lineage power representative for more details.
