FRSM Series of Z-1 Foil Chip Resistors

Vishay Foil Resistors' Z-1 foil ultra-high precision wrap-around chip resistor for improved load life stability

Image of Vishay Foil Resistors' FRSM Series of Z-1 Foil Chip ResistorsThe FRSM series is based on the new generation Z-1 technology of the Bulk Metal® Precision Foil resistor elements by Vishay Foil Resistors, 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 25 KV 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 175°C. Resistance patterns are photo-etched to permit trimming of resistance values to very tight tolerances.
