Question During electrostatic discharge what radio wave spectrum is being induced to propagate in space ? –Russel Maguad, Manila, Philippines
Answer An ESD Event can generate EMI from under 1 megahertz to well over 5 gigahertz depending on several factors such as materials, surface topology, arc spacing, charge density, etc.Typical HBM ESDs can have pulse widths between 5 ns and 200 ns with rise times much less than 1 ns. This yields frequency of 5 megahertz to 200 megahertz, but rise times can be faster then 1 picosecond yielding frequencies over 1 gigahertz.
