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

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.
