NOTES
1) Pins 1-4, 6-8, A-C are 0.040” (1.02mm) diameter. with
0.080” (2.03mm) diameter standoff shoulders.
2) Pins 5 and 9 are 0.080” (2.03 mm) diameter with
0.125” (3.18mm) diameter standoff shoulders.
3) Pins 3, A, B & C only included in Full-Feature models.
4) Other pin extension lengths available. 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: 1.8 oz. (51g) 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 consid-
ered part of the input/primary circuit.
