INTRODUCTION
The Z201 (0.150" lead spacing) and Z201L (0.200" lead
spacing) Bulk Metal
®
Z-Foil resistors represent an industry
breakthrough. This is the 3rd in a series of ultra-precision
resistors since the first Bulk Metal
®
Foil resistor was
introduced by Vishay in 1962. Each represents an
improvement on the earlier model. The TCR slope of the
Z201 is 0.2 ppm/°C (- 55 °C to + 125 °C, + 25 °C Ref.) and is
an order of magnitude better than the original S102C. The
Bulk Metal
®
Z-Foil resistor is the ultimate choice in the most
demanding analog applications.

The Z-Foil technology provides a significant reduction of the
resistive component’s sensitivity to ambient temperature
variations (TCR) and applied power changes (PCR).
Designers can now guarantee a high degree of stability and
accuracy in fixed-resistor applications using solutions based
on Vishay’s revolutionary Z-Foil technology.
Our Application Engineering Department is available to
advise and to make recommendations. For non-standard
technical requirements and special applications, please

IMPROVED PERFORMANCE TESTING
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 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.
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.
