Electromagnetic pulse grenade

An electromagnetic pulse grenade (EMP) grenade, also called a droid popper, was a type of grenade that utilized electromagnetic emissions. They could be used to disable a battle droid's circuits or to incapacitate humans. When used against stormtroopers, it overloaded their armor electronics, though its effectiveness depended on distance and placement relative to the target. They were used by the Jedi and their clone troopers against the Separatist Droid Army during the Clone Wars.
