(see figure 1). if you want to further decrease the input/output ripple, you can increase capacitance properly or choose capacitors with low esr. however, the capacitance of the output filter capacitor must be proper. if the capacitance is too big, a startup problem might arise. for every channel of output, provided the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor sees (table 1). general: cin: 24v&48v 10 f -47 f cout: 10 f /100ma input input input input current current current current when it is used in unregulated power supply, be sure that the fluctuating range of the power supply and the rippled voltage do not exceed the module standard. input current of power supply should afford the startup current of this kind of dc/dc module (see figure 2), general: ip 1 .6*iin-max no no no no parallel parallel parallel parallel connection connection connection connection or or or or plug plug plug plug and and and and play. play. play. play. mechanical dimensions note: unit:mm[inch] pin diameter tolerances: 0.10mm[ 0.004inch] general tolerances: 0.25mm[ 0.010inch] footprint footprint footprint footprint details details details details pin pin pin pin single single single single dual dual dual dual 2,3 gnd gnd 9 no pin 0v 11 nc -vo 14 +vo +vo 16 0v 0v 22,23 vin vin nc: no connection. recommended footprint(top view) tube outline dimensions note: unit :mm[inch] general tolerances: 0.50mm[ 0.020inch] l=530mm[20.866inch] tube quantity: 15pcs l=220mm[8.661inch] tube quantity: 6pcs
