I'm looking to use a device that would function as a fuse. However, I need a device that can withstand high voltage (~5 kV), but to limit the current to ~40 mA. I've found fuses that can limit in the mA range, however the max voltage is in the V range. I've also found high voltage fuses, however they limit in the A range. Does anyone know of anything that would work for my specifications? Thanks!
