Place the DC input pattern awayfrom the power module.Do not pass the DC output pattern underneath the power module as this will increase output noise. Place the DCoutput pattern away from the power module.!High frequency noise is radiated from the power module. When mounting the power module on a PCB, leave a copper pattern on the PCBto let it act as a shield and connect this pattern to the mounting hole.!Avoid placing pattern layout in hatched area shown in right fi gure to insulatebetween pattern and power supply.5.048.5+VINRC-VIN+VOUT+STRM-S-VOUT?CQHS300/CQHS350!Soldering CQHS series with printed board must be done under the fl at conditionby using the mounting hole and fi xing with the screw.If CQHS series is inclined and it’s mounted, the insulation of the internal componentsand printed board might not be kept.!When a heat sink cannot be fixed on the base plate side, order the powermodule with“-T”option. A heat sink can be mounted by affi xing a M3 tap onthe heat sink.Please make sure a mounting hole will be connected to a grounding capacitorCY.CQHS-8? 526 ?StandardOptional : -TMounting holeM3 tappedf3.4 thru
