NOTES
1) Pins 1-3, 5-7 are 0.040” (1.02mm) diameter with
0.080” (2.03 mm) diameter standoff shoulders.
2) Pins 4 and 8 are 0.062” (1.57 mm) diameter with 0.100”
(2.54 mm) 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 (RoHS 5/6) - Tin/Lead over Nickel plate
Finish (RoHS 6/6) - 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: 1.5 oz. (42 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) The flanged pins are designed to permit surface mount soldering (allow-
ing to avoid the wave soldering process) through the use of the flanged
pin-in-paste technique.

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