Electro-Pyrotechnic Initiator Chip Resistor
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.
PRINCIPLE OF OPERATION
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

FEATURES
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
Pb-free
Available
RoHS*
COMPLIANT
• Firing time down to 50 µs
• Ohmic range: 2R to 10R
• 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
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.

MECHANICAL SPECIFICATIONS
• Substrate: Special alumina based substrate
• Resistive element: Fine line patterned Tantalum nitride thin
film layer
• Diffusion and conductive thin film layers
• Terminations: Wraparound over nickel barrier
TECHNOLOGY
This technology contributes to the stability of the heating element, the precise electro-thermal response profile and the ability to
design a precise activation energy.
All these features are perfectly controlled on high production volumes.
* Pb containing terminations are not RoHS compliant, exemptions may apply
