Massive Electro-Pyrotechnic Initiator Chip Resistor MEPIC Vishay Sfernice
●The Massive Electro-Pyrotechnic Initiator Chips (MEPIC) are resistors dedicated to pyrotechnic applications. The MEPIC resistors are the Surface Mount Device (SMD) variants from the established NiCr on FR type substrate technology from Vishay Sfernice. The standard case geometry (SMD) enables the implementation of assembly process commonly used in the electronic component industry (pick and place, reflow soldering on flat PCB used as header) providing high productivity. The principle of MEPIC is to convert electrical energy into heat in a precise electro-thermal profile for the purpose of initiating a series of pyrotechnic events in a controlled energetic reaction. In the mining industry this effect is commonly used for the ignition of electronic detonators (digital blasting). Other industries such as firework (e-match manufacturing) and demolition (various electric detonators) are also focused applications.
The MEPIC design has been developed specifically to offer an alternative to the Bridge Wire (BW) technology, insuring at least the same level of performances, while providing cost efficient assembly process and initiator design alternatives.
