ESCC (

) 4001/023 Qualified R Failure Rate High Precision

(10 ppm/°C, 0.05 %) Thin Film Chip Resistors

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).
