60 Revision: 15-Nov-07
For low noise and precision applications, superior stability,
low temperature coefficient of resistance, and low voltage
coefficient, VISHAY SFERNICE’s proven precision
thin film wraparound resistors exceed requirements of
MIL-PRF-55342G characteristics Y ± 10 ppm/°C (- 55 °C;
+ 155 °C) down to ± 5 ppm/°C (- 25 °C; + 85 °C).
FEATURES
•Load life stability at ± 70 °C for 2000 h:
0.1 % under Pn/0.05 % under Pd
•Low temperature coefficient down to 5ppm/°C
(- 25 °C; + 85 °C)
•Very low noise < 35 dB and voltage coefficient
< 0.01 ppm/V
•Resistance range: 10 Ω to 3 MΩ depending on size
•Extended ohmic value range (see table)
•Tolerances to ± 0.01 %
•In lot tracking ≤ 5 ppm/°C
•Termination: thin film technology
•Gold plated or pre-tinned terminations over nickel barrier
•Short circuits (jumpers) r < 50 mR, I < 2 A
DIMENSIONS in millimeters [inches]
Note:
(1) Pn = nominal power - Pd = derated power intended to improve stability
Note:
• Using special NiCr and CrSi alloys we are able to extend the ohmic value range as indicated above.
* Pb containing terminations are not RoHS compliant, exemptions may apply
