Design Considerations for Improving ESD Performance
The flange on the lens has been designed to increase
the creepage and clearance distance for electrostatic
discharge. The table on the right shows typical values
assuming base plate construction per the Avago
supplied IGES file and HDNS-2100 lens flange.
For improved ESD performance, the lens flange can be
sealed (i.e. glued) to the base plate. Note that the lens
material is polycarbonate and therefore, cyanoacrylate-
based adhesives or other adhesives that may damage
the lens should NOT be used.
The trimmed lens, HDNS-2100#001, is not recommend-
ed for corded applications due to the ESD spec require-
ment.
