Abstract: The present invention comprises a capacitor, of sufficient area to cover the glass seal of a cartridge actuated ordnance device, comprising a low pass filter. This capacitor connects to the leads of the cartridge actuated ordnance device in a fashion that covers the glass seal of the cartridge. Although the capacitor is not directly contacting the glass seal, it is located proximately so that very few frequencies of EMR can enter the seal, wherein a safe level of EMR is achieved. The capacitor also filters both EMR and ESD that come through the leads of the cartridge.

Abstract: An electromagnetic flux suppression includes a three stage filtering system to protect against electromagnetic interference and electrostatic discharge and has a first stage high voltage section that filters a high voltage pulse by providing a spark gap to ionize the ambient air and thus effectively form a shunt. A second stage filter has a front end capacitive interface followed by an inductive line to filter out radio frequency arcing that occurs between two bodies thus exposing them to radio frequency radiation. A third stage filter includes a radio frequency low pass filter to reinforce the capacitive inductance filter.
