DHS-seriesImplementation・Mounting MethodStress onto the pins-VOUT!Applying excessive stress to the input or output pins of the powermodule may damage internal connections. Avoid applying stress inexcess of that shown in right fi gure.!Input and output pins are soldered onto the internal PCB. Do notbend or pull the leads with excessive force.!As unexpected stress may be applied to the pins, set the diameterof the PCB mounting hole at 3.5mm.!As unexpected stress may be applied to the pins from vibrationor shock, fix the power module by using the mounting holes withscrews to reduce stress.!Fix the power module to the PCB with the screws before solderingthe input and output pins to prevent the PCB pattern being damaged.-VINRC+VIN-VINRC+VINDHS50, DHS100TRM+VOUT*bottom view-VOUT-STRM+S+VOUTDHS200, DHS250*bottom view+VOUT, -VOUTOthersLess than39.2N(4kgf)Less than39.2N(4kgf)Less than19.6N(2kgf)Less than19.6N(2kgf)Less than39.2N(4kgf)Less than19.6N(2kgf)Soldering temperature!Flow soldering : 260C for up to 15 seconds.!Soldering iron (26W) : 450Cfor up to 5 seconds.DHSDerating!Use the power modules with conduction cooling (e.g. heat dissipation from the aluminum base plate to the attached heat sink).Belowshows the derating curves with respect to the aluminum base plate temperature. Note that operation within the hatchedareas will cause asignifi cant level of ripple and ripple noise.!Please measure the temperature on the aluminum base plate edge side when you cannot measure the temperature of the center part ofthe aluminum base plate.In this case, please take 5deg temperature margin from the derating characteristic of below.!It is necessary to note the thermal fatigue life by power cycle. Please reduce the temperature fl uctuation range as much as possible whenthe up and down of the temperature are frequently generated. Contact us for more information on cooling methods.?
