ESCC ( ) 4001/023 Qualified High Precision (5 ppm, 0.01 %),
High Stability (0.02 %) Thin Film Chip Resistors
SPACE APPLICATIONS ONLY
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).
FEATURES
•Load life stability at ± 70 °C for 2000 h:
0.15 % under Pn
•Low temperature coefficient down to ± 10 ppm/°C
•Very low noise (< 35 dB) and voltage coefficient
(< 0.01 ppm/V)
•Resistance range: 50 Ω to 1 MΩ (depending on size)
•Laser trimmed tolerances to ± 0.01 %
•TCR in lot tracking ≤ 5 ppm/°C
•Termination: Thin film technology
•SnPb terminations over nickel barrier
•ESCC 4001 issue 1 (generic spec)
•ESCC 4001/023 issue 3 (detailed spec)
DIMENSIONS
Notes:
(1) Level C is our standard level. Serialization, which is compulsory on Level B, is very difficult to implement. For Level B, 13 extra pieces shall
be ordered for destructive TCR measurements.
(2) Tape and reel not available for level B
