Bulk Metal® foil technology, first introduced by Vishay in 1962,
still out-performs all other resistor technologies available for
applications that require precision and stability. Vishay's unique,
ultra-precision Bulk Metal foil resistor products provide extremely
low temperature coefficient of resistance (TCR) and exceptional
long-term stability through temperature extremes. Vishay has grown
from being a leader in one area — Bulk Metal foil resistive
products — to being a leader in passive components and discrete
semiconductors. Nevertheless, Vishay continues to develop, manufacture,
and market new types of foil resistor products, including military-established-reliability
components.
The Vishay Foil Resistors portfolio comprises discrete resistors
and resistor networks in surface mount and through-hole (leaded)
configurations, precision trimming potentiometers, and discrete
chips for use in hybrid circuits. Customized chip resistor networks
and resistor arrays can also be manufactured.
The Vishay Foil Resistors flip chip is one of the more recent
developments and represents the next generation of packaging.
In the flip chip, the resistive element is mounted facing the
board and is self-protected. This is a more cost-effective solution
for high volume, analog applications where high precision is required.
The chips typically have power capability that is 50% higher than
standard surface-mount chips.
