When two or more power supplies are used side by side, position them with proper intervals toallow enough air ventilation. The temperature around each power supply should not exceed the temperature range shown in“Derating”.Automatic Mounting!To mount BRNS series automatically, use the coil area near the center of the PCB as an adsorption point. Please see the External View fordetails of the adsorption point.(C)Soldering!Right figure shows condition for reflow of BRNS series. Pleasemake sure that the temperature of board’s pattern near by +VOUTand GND terminal.!While soldering, having vibration or impact on the unit should beavoided, because of solder melting.!Please do not do the implementation except the refl ow.!Because some parts drops, please do not do reflow of the backside.TpTxTy2Ty1, ,A A B B CBRNS-4? 464 ?time(s)A 1.0 - 5.0C / sA’Ty1 : 160 10CTy2 : 180 10CTy1 - Ty2 : 120s maxB 1.0 - 5.0C/ sB’Tp : Max245C 10s maxTx : 220C or more : 70s maxC 1.0 - 5.0C / s
