Typical Pin Depth Values
The pin depth value of each device is not specified, but is an important mechanical
parameter. The electrical performance of the device depends, to some extent, on its
pin depth. The electrical specifications for each module takes into account the effect of
pin depth on the device’s performance. The following tables list the typical pin depths
and measurement uncertainties, and provides observed pin depth limits for the
devices. If the pin depth of a device does not measure within the observed pin depth
limits, it may be an indication that the device fails to meet electrical specification.
