FRSM Series of Precision Chip Resistors
Vishay Foil Resistors
Z-1 Foil Ultra High Precision Wrap-around Chip Resistor for
Improved Load Life Stability of 0.0025% (25 ppm) with TCR of
± 0.05 ppm/°C and withstands ESD of 25 KV min
Top View
INTRODUCTION
The FRSM is based on the new generation Z1- technology of
the Bulk Metal® Precision Foil resistor elements by Vishay
Precision Group (VPG), which makes these resistors
virtually insensitive to destabilizing factors. Their element,
based on the new Z-1 Foil is a solid alloy that displays the
desirable bulk properties of its parent material; thus, it is
inherently stable (remarkably improved load life stability of
25 ppm), noise-free and withstands ESD to 25KV or more.
The alloy is matched to the substrate and forms a single
entity with balanced temperature characteristics for an
unusually low and predictable TCR over a wide range from
-55 C° to more than 175C°. Resistance patterns are
photo-etched to permit trimming of resistance values to very
tight tolerances.
Our application engineering department is available to
