NOTES
1) M3 screws used to bolt unit’s baseplate to other surfaces (such
as heatsink) must not exceed 0.100” (2.54 mm) depth below
the surface of the baseplate.
2) Applied torque per screw should not exceed 6in-lb. (0.7 Nm)
3) Baseplate flatness tolerance is 0.004” (.10mm) TIR for surface
4) Pins 1, 2, 4, 6-8, are 0.040” (1.02mm) diameter with 0.080”
(2.03mm) diameter standoff shoulders
5) Pins 5, 9 are 0.080” (2.03mm) diameter shoulderless pins.
6) Other pin extension lengths available
7) All Pins: Material - Copper Alloy
Finish (RoHS 5/6) - Tin/Lead over Nickel plate
Finish (RoHS 6/6) - Matte Tin over Nickel plate
8) Undimensioned components are shown for visual reference only.
9) Weight: 4.3 oz. (123 g) typical
10) All dimensions in inches (mm)
Tolerances: x.xx +/-0.02 in. (x.x +/-0.5mm)
x.xxx +/-0.010 in. (x.xx +/-0.25mm)
