The VSMP1206 Precision Surface Mount Chip Resistor utilizes Ultra Precision Bulk Metal(R) Z Foil (BMZF) Vishay's revolutionary for the resistive element. This technology provides a significant reduction of the resistive components' sensitivity to ambient temperature variations and applied power changes. Designers now can guarantee a high degree of stability an accuracy in fixed - resistor applications using solutions based on BZMF technology. The new technology provides inherently an extremely low and predictable Temperature Coefficient of Resistance (TCR), a remarkably improved load life stability, low noise and availability of tight tolerance. The TCR is a process capability not a selection process and for most of the range is independent of ohmic value and lot related variations. A voltage divider can be fashioned by using two arbitrarily selected VSMP1206s with a resultant tracking specification of < 3ppm/C. Extremely low tracking of < 1ppm/C can be supplied upon request. The VSMP1206 has a conventional full wrap around robust termination which insures safe handling during manufacturing process, as well as providing stability during the multiple thermal cyclings it will see over its service life. The availability of tight absolute tolerance provides a good cost solution for the variability of other components when compiling the total error budget. BMZF offers the best stability available; and is more than an order of magnitude better than thin film technology. The noise generated by the resistor is non measurable and its design and construction make it well suited for high frequency applications. The BMZF is the ultimate resistor component for analog applications. Most effective in applications where high stability is required under load and extreme enviromental conditions.
