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) diameter 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: 10 oz. (284 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.
10) Applied torque per screw should not exceed 3 in-lb (.33Nm)

Pin Designations Notes:
1. Leave TRIM pin open for nominal output voltage.
2. SENSE(+) should be connected to Vout(+) either remotely or at the converter.
3. SENSE(–) should be connected to Vout(–) either remotely or at the converter.
