Abstract
An improved electro-explosive squib device is disclosed with filter/shield characteristics rendering the device substantially immune to electromagnetic environments, thus preventing accidental ignition of the squib device. The invention provides for adapting existing squibs or constructing new squibs with immunity to the electromagnetic environments while adding only a minimal amount of material to the device, thus minimizing the possibility of personnel injury caused by debris ejected from rocket propellant ignited by the squib device. These benefits are achieved while maintaining reliability and extended shelf life, and at minimal cost of conversion or manufacture of the squib devices.
