Vishay Foil Resistors High Precision Foil Resistor with TCR of ± 2.0 ppm/°C, Tolerance of ± 0.005 % and Load Life Stability of ± 0.005 %
STANDARD OPERATIONS AND TEST IMPROVED PERFORMANCE TESTING (IPT) CONDITIONS
A. Standard Test Operations: The preceding information is based on product directly off the production line. Improved performance (meaning By 100 % Inspection • increased time stability with load and other stresses) is Short-time overload (6.25 x rated power for 5 s) available through factory conducted “Improved Performance • Resistance – tolerance check Testing”. The test routine is usually tailored to the users • Visual and mechanical stability objectives and product that has been screened can By Sample Inspection be brought down to a potential load life of less than 50 ppm. • TCR • Environmental tests per table 3 on a quarterly basis to Various screen test routines are available and all anticipated establish performance by similarity stresses must be taken into account before settling on one B. Standard Test Conditions: specific test routine. Our Applications Engineering • Lead test point: 0.5" (12.7 mm) from resistor body Department is prepared to discuss and recommend • Temperature: + 23 °C ± 2 °C appropriate routines given the full spectrum of anticipated • Relative humidity: per MIL-STD-202 stresses and stability requirements.

Load life at 2000 h ± 0.015 % (150 ppm) Maximum ΔR at 0.3 W/+ 125 °C ± 0.005 % (50 ppm) Maximum ΔR at 0.1 W/+ 70 °C Load life at 10 000 h ± 0.05 % (500 ppm) Maximum ΔR at 0.3 W/+ 125 °C ± 0.01 % (100 ppm) Maximum ΔR at 0.05 W/+ 125 °C
Current Noise
0.010 µV (RMS)/V of applied voltage (- 40 dB)
High Frequency Operation
Rise time 1.0 ns at 1 kΩ Inductance (L)2) 0.1 µH maximum; 0.08 µH typical Capacitance (C) 1.0 pF maximum; 0.5 pF typical
Voltage Coefficient
< 0.1 ppm/V3)
Thermal EMF4)
0.1 µV/°C Maximum; 0.05 µV/°C typical 1 µV/W (Model S102C)
Notes
1. Load life ΔR maximum can be reduced by 80 %, please contact Applications Engineering Department. 2. Inductance (L) due mainly to the leads. 3. The resolution limit of existing test equipment (within the measurement capability of the equipment, or “essentially zero”.) 4. µV/°C relates to EMF due to lead temperature difference and µV/watt due to power applied to the resistor. www.vishay.com For any questions, contact: foil@vishay.com Document Number: 63001 4 Revision: 20-Nov-07 Document Outline Datasheet Disclaimer
