How would you even insulate them? They are metal cages, with solid state components and no way to discharge the pulse. Vacuum is not a terribly good conductor.

Only way I can think of, off the top of my admittedly sleep lacking brain, is to stick a small ion rocket in the satellite. Tiny one - a millionth of a G thrust - but enough to disperse the charge before things fry. It's play hell with the orbits, but better to have a sat on a new orbit than a lump of metal that doesn't respond at all.

The satellites are equipped with special chips.The first method is metallic shielding. Shields are made of a continuous piece of metal such as steel or copper.The second method, tailored hardening, is a more cost-effective way of hardening.

EMP is small change.  If you really want to take out someone's satellite with a nuke, first time, every time, you use that nuke to fire a pumped x-ray laser and fire a few million mega-joules worth of hard radiation at the target and blow it into lots of little glowing pieces...

Best thing to take out a satellite is another one. I know that both the USSR and the USA still have hunter killer sats in orbit, designed to take out communications sats and spy sats. They are small, overfueled and normally just orbit in standby mode.

You mean ASATs. The U.S. is experimenting with them.On February 21, 2008, USA destroyed a malfunctioning U.S. spy satellite USA-193 using a RIM-161 Standard Missile 3(Operation:Burnt Frost). In 2007, the Chinese successfully destroyed a defunct Chinese weather satellite, FY-1C in 2007
