Vishay - Bulk Metal® Foil

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.
