Initiator resistor specifically designed for pyrotechnic applications

Specifically designed for pyrotechnic applications and offering predictable, reproducible and reliable behaviour that meets USCAR and AKLV16 standards, Vishay's MEPIC SMD (0805) initiator resistor is now available from Farnell element14. The industry's first massive electro-pyrotechnic initiator chip (MEPIC) it converts electrical energy into heat energy in a precise electro-thermal profile in order to initiate pyrotechnic events in a controlled energetic reaction. Example applications include the mining industry, for the ignition of electronic detonators (digital blasting). They can also be used in other industries such as firework (e-match manufacturing) and demolition (various electric detonators). The MEPIC design has been specifically made to offer an alternative to traditional bridge-wire (BW) technology, ensuring at least the same level of performance, while providing cost-efficient assembly process and initiator design alternatives. The two main characteristics of a MEPIC resistor are their 'All Fire' (AF) and 'No Fire' (NF) performances: All Fire (AF) represents the command pulse where the major amount of the dissipated energy will be transferred to the primer to generate the ignition. No Fire (NF) represents the immunity of the resistor with primer to the environmental electro-magnetic pollution and electric continuity test, where the major amount of the dissipated energy will be transferred to the substrate to ensure no ignition.
