VSM0805
Vishay Foil Resistors
The VSM0805 represents the latest addition and smallest size
to the Precision Bulk Metal
mount chip resistor series. The VSM0805 has a conventional
full wrap around termination.
The BMF technology offers designers the lowest and most
predictable absolute Temperature Coefficient Resistance
available. The TCR is a process capability not a selection
process and for the most part is independent of ohmic value
and lot related variations.
The availability of tight absolute tolerance provides a good cost
solution for the variability of other components when compiling
the total error budget. BMF offers the best stability available;
and is 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 BMF is the ultimate resistor component for
analog applications.
