Hello, for my capacitive discharge ignition I need to place the pulse capacitor near the MPU (the space is very small and in the end they'll have to share it). Will this guarantee interference on the MPU? Or the capacitor is "shielded" by itself and won't cause much interference? (i.e. the wire will of course, but not the capacitor itself, so I can run the wire with a ground guard and minimize its effects, but if the capacitor body radiates, it will be useles= s). Pulse is about 50A for 20us, pretty intensive. Many thanks for Your hints.
