E _{STANDARD MEASUREMENT (at room temperature)}
Standard Test Conditions:
V _{• Temperature: + 23 °C ± 2 °C}
• Relative humidity: 35 to 65 % RH
• Lead test point: 0.5" (12.7 mm) from resistor body
O _{IMPROVED PERFORMANCE TESTING}
R _{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
P ^{is usually tailored to the user’s stability objectives. A screened product can be brought down to a potential load life drift of less}
than 50 ppm.
For example, the data sheet “7 Technical Reasons to Specify BMF Resistive Components” shows the drift characteristics of a
standard product.
IM ^{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 available to discuss and recommend appropriate routines given the full
spectrum of anticipated stresses and stability requirements.
