MECHANICAL DIAGRAM (open frame)
NOTES
1) Pins 1-4, 7-12 are 0.040” (1.02mm) diameter, with 0.080” (2.03mm) diameter
standoff shoulders.
2) Pins 5-6, 13-18 are 0.080” (2.03 mm) diameter with 0.125” (3.18mm) diam-
eter standoff shoulders.
3) Other pin extension lengths available. Recommended pin length is 0.03”
(0.76mm) greater than the PCB thickness.
4) All Pins: Material - Copper Alloy
Finish - Matte Tin over Nickel plate
5) Undimensioned components are shown for visual reference only.
6) All dimensions in inches (mm)
Tolerances: x.xx +/-0.02 in. (x.x +/-0.5mm)
x.xxx +/-0.010 in. (x.xx +/-0.25mm)
7) Weight: 5 oz. (142 g) typical
8) Workmanship: Meets or exceeds IPC-A-610C Class II
9) 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.
