Bulk Metal® Foil Technology out performs all other resistor technologies available today for applications that require high precision and high stability.

This technology has been pioneered and developed by VISHAY, and products based on this technology are the most suitable for a wide range of applications.

Generally Bulk Metal® Foil technology allows us to produce customer orientated products designed to satisfy challenging and specific technical requirements.

The VSR Series of resistors is a low cost version of the well established S-Series of resistors. These resistors are made of foil elements so all of the inherent performance of foil is retained. They do not however, have the same TCR or tolerance ranges (see table 1 for details). These products find a wide range of usage in high end stereo equipment and some grades of test and measurement equipment.

VSR Series are dimensioned to provide a minimum lead clearance of 0.010 inches between the resistor body and the printed circuit board, when the standoffs are seated on the board. This allows for proper cleaning after the soldering process.
