Massive Electro-Pyrotechnic Initiator

AEC-Q200 Qualified Resistor Chip

DESIGN SUPPORT TOOLS

MEPIA is the AEC-Q200 qualified declination of Vishay

MEPIC product.



The principle of MEPIA is to convert electrical energy into

heat in a precise electro-thermal profile. Automotive

applications cover airbags and security belts activation.

FEATURES

• AEC-Q200 qualified

• Surface mount design for standard assembly

process

• SMD version only, with tin terminations

• Case size 0805

• Firing time down to 250 μs

• Ohmic value: 2



• Joule effect ignition

• Easy set up by design of firing levels

• Very predictable, reproducible and reliable behavior

• Compatibility with pyrotechnic element has to be tested in

real environment

• Material categorization: for definitions of compliance

Note

chemistry and active areas geometry

Notes

• For the assembly on board, we recommend the lead (Pb)-free thermal profile as per J-STD-020C

• Do not use iron soldering method to mount a MEPIA because it may damage the component (deformation that may cause active area cracks)
