NOTES
1) Pins 1-3, 5-7 are 0.040” (1.02mm) diameter. with 0.080”
(2.03mm) 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 - Tin/Lead 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: 0.68 oz. (19 g) typical
8) Workmanship: Meets or exceeds IPC-A-610C Class II
9) Modules ordered as an EGA option have different pins to pro-
vide a minimum bottom side clearance of 0.076” while increas-
ing maximum height to 0.424”. See ordering page for more
information.
10) The flanged pins are designed to permit surface mount
soldering (allowing to avoid the wave soldering process)
through the use of the flanged pin-in-paste technique.
