- Vishay Foil Resistors is a product brand of Vishay Precision Group (VPG), producing the most precise and stable resistors available. VPG is an NYSE company that was a recent spin-off from Vishay Intertechnology, Inc. The unique Bulk Metal® Foil technology by Vishay Foil Resistors outperforms all other resistor technologies due to its extremely low temperature coefficient of resistance (TCR) and exceptional load life stability through temperature extremes. Our product portfolio includes discrete resistors and resistor networks in surface mount and through-hole (fixed-lead) configurations, customized chip resistor networks, precision trimming potentiometers, and discrete chips for use in hybrid circuits. These devices are used in applications requiring a high degree of precision and stability such as in medical testing equipment, semiconductor equipment, precision measuring instruments, aerospace, and military applications.
CSM3637Z Current-Sensing Resistors
Vishay's current-sensing resistor has improved resistance stability and features a low thermal electromotive force critical for DC applications.
FRSM Series of Z-1 Foil Chip Resistors
Vishay resistors are constructed of solid alloy, making them insensitive to destabilizing factors.
Vishay's ultra-high precision, Z-Foil audio resistor is designed to improve sound quality by reducing audible distortion.
Z201 Bulk Metal® Foil Resistor
Vishay's Z201 Bulk Metal foil resistor combines the lowest ever TCR with tolerance to 0.005%, making it ideal for applications needing precision.
Bulk Metal® Trimmers
Vishay trimmers have inherent temperature and load life stability. Lash-free adjustment mechanism allows them to be set quickly and accurately.
CSM Series Resistors
Vishay's resistors have low absolute TCR that reduce errors that occur due to temperature gradients.
