Vishay Sfernice
EXAMPLE OF APPLICATION
Chip: 0603
R: 2R ± 0R2
Energy: Around 1.5 mJ
Response time: 0.2 ms
Mounting Recommendations
EPIC can be mounted either on a PCB or on a squib. Please refer to Application Note (http://www.vishay.com//doc?53044) to
see Vishay/Sfernice recommendations.
AIRBAGS INITIATORS
A prerequisite to valid reliability estimation of an electro-explosive device (EED) is a sensitivity test program carefully chosen and
properly perform. The Bruceton Method (or up and down method) of sensitivity testing was developed specifically for ordinance
testing. Here under is an example of Bruceton’s test results.
2 customers: Customer A and customer B have equipped squibs of their own with 3 variants (Variant 1, 2 and 3) . Bruceton’s test
results of Vishay heating elements are shown in Table 1

CONCLUSION
Bruceton test results are self explanatory. They show that the electro-thermal behavior of EPIC is predictable, precise and
reproducible.

HOW TO GET THE RIGHT EPIC
Each EPIC will have to be adapted to customer pyrotechnic element. To reach the right product, Vishay/Sfernice works by
“iteration”. Upon receipt of the EPIC Design Guide (http://www.vishay.com/doc?53045) duly filled, an initial sampling lot is given
to customer (along with an EPIC reference) so he can provide Vishay/Sfernice with “no firing”/“all firing” conditions.
Then Vishay/Sfernice will be able to provide a new set of samples (eventually tooling charges will be necessary). Ohmic value of
samples will remain the same, but there will be a new compromise between the length, the width and the thickness of the filament
so as to increase the sensitivity of the EPIC and adapt the firing conditions to the pyrotechnic element of the customer.
When the right parameters are reached Vishay/Sfernice will design a final set of mask (with the participation of the customer).

Notes
(1) Tin/lead: Please consult
• EPIC being a semi-custom product, please fill EPIC Design Guide (http://www.vishay.com/doc?53045) and send to
sfer@vishay.com to get appropriate part number.
• Per Vishay policy all the components designed for automotive applications should be tested in accordance to AEC Q200
specification. As the EPIC is just part of an ignitor which is designed and qualified by each customer Vishay is not proceeding
to any AEC Q200 test.
