mounting method ?fixing method in fixing to the pc board, use mounting taps at two places in the side of the lower surface (terminal side). use m4 screws for fixing and pay attention not to insert the screws 6mm or deeper from the surface of the body (recommended clamping torque: 1.08n m). in fixing a radiator, use mounting taps at two places in the upper surface of the case (aluminum plate side). use m3 screws for fixing and pay attention not to insert the screws 6mm or deeper from the surface of the body (recommended clamping torque: 0.69n ?m). in addition, it is recommended to use thermal conducting grease to enhance a radiating effect between the radiator and the power supply body (aluminum surface) when mounting. ?pattern width large current flows into the input-output pattern. it may cause a voltage drop or heat developed. be very careful with designing the pattern. the pattern width should be determined on the basis of a reference value of 1mm/a. ?recommended soldering conditions dip: 2305?, 5s ?recommended cleaning conditions partially clean the pc board pattern surface. the recommended conditions are as follows: cleaning fluid: ipa cleaning method: brush cleaning * see that the cleaning fluid does not permeate into the inside of the power supply. it may cause a trouble. characteristics, functions, and applications tdk switching power supply a222_spm (11/12) all specifications are subject to change without notice.
