CQHS-seriesImplementation・Mounting MethodStress onto the pins!Applying excessive stress to the input or output pins of the power module may damage internal connections. Avoid applying stressin excessof that shown in below.!Input and output pins are soldered onto the internal PCB. Do not bend or pull the leads with excessive force.?CQHS250?CQHS300/CQHS350-VINRC+VIN+VOUT, -VOUT-VOUT-STRM+S+VOUTOthers-VINRC+VIN-VOUT-STRM+S+VOUTLess than19.6N(2kgf)Less than19.6N(2kgf)Less thanLess than19.6N19.6N+VOUT, -VOUTOthersLess than39.2N(4kgf)Less than39.2NLess than19.6N(2kgf)Less than19.6N(2kgf)Less than9.8N(1kgf)Less than9.8N(1kgf)Less than39.2N(4kgf)Less than19.6N(2kgf)?CQHS300/CQHS350!As unexpected stress may be applied to the pins, set the diameter of the PCB mounting hole at 3.5mm.!As unexpected stress may be applied to the pins from vibration or shock, fi x the power module by using the mounting holes screws to reducestress.!Fix the power module to the PCB with the screws before soldering the input and output pins to prevent the PCB pattern being damaged.Soldering temperature!Flow soldering: 260C for up to 15 seconds.!Soldering iron (26W): 450C for up to 5 seconds.CQHSDerating!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.?CQHS250!Use with the convection cooling or the forced air cooling. Make sure the temperatures at temperature measurement locations shown beloware on or under the derating curve.
