Abstract
An ignition device for a safety system such as an air bag or seat belt tightener for a motor vehicle having an ignition element and associated EMC protection means. The EMC protection means may comprise an EMC suppression comprising a ferrite core, which is encapsulated resistant to pressure. Encapsulation in a pot-like housing or between two half shells, with or without an intermediate coating, aids pressure resistance. Terminal means, such as terminal contacts or lugs, extends through the encapsulation to operatively connect the ignition element and the system's controls.
