AND TEC I INNOVAT O L OGY EPIC Vishay Sfernice N HN CHIP RESISTOR EPIC O 19 62-2012 Electro-Pyrotechnic Initiator Thin Chip Film Chip Resistor Electro-Pyrotechnic Initiator Resistor Vishay has developed a special thin film resistor chip specifically designed to provide pyrotechnic engineers with a lot of advantages Firing energy down to 50 µJ Firing time down to 50 µs Ohmic range: 2R to 10R Electro-pyrotechnic initiator resistors, also known as bridge resistors, are resistive elements, which 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 automotive applications this effect is used to deploy automotive airbags and other safety devices. These same devices are also used in military applications for pilot ejection systems, explosive bolt disengagement of airbone missiles, chaff dispensers, artillery projectile activators, anti-tank mines, etc. Commercially, they are used in mining and de-constructions applications. Compatibility with various pyrotechnic composition even with no primer Joule effect ignition 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 behaviour Size: 0603 preferred - other size available upon request Compliant to RoHS directive 2011/65/EU PRINCIPLE OF OPERATION and longest duration when part should not ignite the explosive powder. “All fire” represents the command pulse. Customer will have to provide Vishay Sfernice with “all firing” conditions: Minimum current, duration necessary to ignite the explosive powder. The two main parameters of an EPIC are “no fire” and “all fire” conditions. “No fire” represents the immunity of the resistor to the environmental electro-magnetic pollution and electric continuity test: Therefore customer will have to provide Vishay Sfernice with “no firing” conditions: Maximum current DIMENSIONS in millimeters (inches) A B C DIMENSION CASE SIZE 0603 A B C MAX.
