COSEL Power Supply, Noise Filter 2025 Product Catalog

DCS-seriesImplementation・Mounting MethodStress onto the pins!When too much stress is applied to the pins may damage internalconnections. Avoid applying stress in excess of that shown in rightfi gure.!The pins are soldered onto the internal PCB.Therefore, Do not bend or pull the leads with excessive force.!Fix the unit on PCB (fi xing fi ttings) by screws to reduce the stress tothe pins. Be sure to mount the unit fi rst, then solder the unit.Soldering temperature!Flow soldering : 260C for up to 15 seconds.!Soldering iron (47W) : 450Cfor up to 5 seconds.?

Belowshows the derating curves with respect to the aluminum base plate temperature. Note that operation within the hatched areas will cause asignifi cant level of ripple and ripple noise.!Please measure the aluminum base plate temperature at measurement point A as shown in the diagram below.!Please measure the temperature at measurement point B on the aluminum base plate edge side when you cannot measure the aluminumbase plate temperature at measurement point A.In this case, please take 5deg temperature margin from the derating characteristicsshown in below.!Please reduce the temperature fl uctuation range as much as possible when the up and down of the temperature are frequently generated.Contact us for more information on cooling methods.?
