Vishay Sfernice Thin Film division holds ESCC QML
qualification (ESCC technology flow qualification).
These HiRel components are ideal for low noise and
precision applications, superior stability, low temperature
coefficient of resistance, and low voltage coefficient,
VISHAY SFERNICE’s precision thin film wraparound
resistors exceed requirements of MIL-PRF-55342G
characteristics Y (± 10 ppm/°C).

Vishay/Sfernice thin film is the first passive manufacturer to
hold the ESCC Technology Flow Qualification, official
certificate is available on ESCIES web site
https://escies.org/ReadArticle?docId=727).
This qualification open the door to a new concept at ESA:
The Failure Rate option (similar to the one offered in the MIL
system), for instance R failure rate: 0.01 % per 1000 h.
New specifications describing this new concept have been
released by the ESA:
