MEPIC Thin Film Resistors Vishay/Sfernice Massive Electro-Pyrotechnic Initiator Chip (MEPIC) Thin Film Resistors are the Surface Mount Device (SMD) variants designed for pyrotechnic applications. These resistors convert electrical energy into heat in a precise electro-thermal profile to initiate a series of pyrotechnic events in a controlled energetic reaction. The standard case geometry (SMD) enables the implementation of the assembly process used in the electronic component industry to provide high productivity. The MEPIC SMD resistors feature firing energy down to 1.0mJ, firing time down to 250μs, and Joule effect ignition. These resistors are specifically designed to offer an alternative to Bridge Wire (BW) technology with the same level of performance. Typical applications include mining, demolition, and fireworks.
