EPIC Vishay Sfernice Electro-Pyrotechnic Initiator Thin Film Chip Resistor
●The electro-pyrotechnic initiator thin film chips (EPIC) are resistors dedicated to pyrotechnic applications. The EPIC resistors are based on Ta₂N thin film technology deposited on specifically prepared ceramic substrate for optimized dissipation purpose. 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 EPIC is to convert electrical energy into heat energy 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, as the bridge wire (BW) technology, the EPIC is commonly used in electronic detonators (digital blasting) for very precise rock fragmentation. The EPIC resistors are designed for any pyrotechnic application requiring very fast and reproducible ignition.
● FEATURES:
■ Surface Mount Design for standard assembly process
■ SMD version only
■ Active area designed upon performances
■ Case size 0603
■ Firing energy down to 50 μJ
■ Firing time down to 50 μs
■ Ohmic value: 2 Ω to 10 Ω ±15% (typical) (1)
■ Joule effect, or flash ignition for very fast firing
■ Easy set up by design of firing levels
■ “No Fire” / “All Fire” ratio up to 70%
■ Very predictable, reproducible and reliable behavior
■ Compatibility with pyrotechnic element has to be tested in real environment
