"B.12.3 EMP Protection
Electronic equipment can be EMP-hardened. The primary objective of EMP hardening is to reduce the electrical pulse entering a system or piece of equipment to a level that will not cause component burnout or operational upset. It is always cheaper and more effective to design the EMP protection into the system during design development. Potential hardening techniques include using certain materials as radio frequency shielding filters, using internal enclosed protective “cages” around essential electronic components, using enhanced electrical grounding, shielded cables, keeping the equipment in closed protective cases, or keeping the equipment in an EMP-protected room or facility. Normally, the hardening that permits equipment to operate in intense radar fields (e.g., helicopters that operate in front of a ship’s radars) also provides a significant degree of EMP protection."

I wonder how many Helicopter pilots and crews have had children after being in front of the same radars?

EMP protection is not for the circuits, it also has to encompass the wiring between the black boxes and, the power supply. EMP turns transistors (or any P-N junction) into a three way short circuit.
To me the real question is the F-35 EMP hardened more than any past fighters?
Yes, the F-35 and all military aircraft are designed and tested to survive nuclear EMP. There is a test site at NAS Patuxent River, MD which can simulate pulses up to 50kVm, and is used by all three military services. More info here: http://www.navair.navy.mil/nawcad/index ... A04BB0296D
Other types of electrical interference are also tested (known as E3 or 'E cubed'). Aircraft are literally winched of the ground in electrically shielded, anechoic chambers and have all systems tested for interoperability, against lightning strikes, enemy emissions, etc. http://www.navair.navy.mil/nawcad/index ...
