Recommended pin length is 0.03” (0.76mm) greater than the PCB thickness. 5) All Pins: Material - Copper Alloy Finish - Tin/Lead over Nickel plate 6) Undimensioned components are shown for visual reference only. 7) All dimensions in inches (mm) Tolerances: x.xx +/-0.02 in. (x.x +/-0.5mm) x.xxx +/-0.010 in. (x.xx +/-0.25mm) 8) Weight: 2.6 oz. (75g) typical 9) Workmanship: Meets or exceeds IPC-A-610C Class II 10) UL/TUV standards require a clearance greater than 0.04” (1.02mm) between input and output for Basic insulation. This issue should be considered if any copper traces are on the top side of the user’s board. Note that the ferrite cores are considered part of the input/primary circuit. PIN DESIGNATIONS |
