物理学家Felix Zandman博士于1962年发明了超过四十五年后，BulkMetal®箔（BMF）技术仍然优于当今所有其他电阻技术，适用于要求精度，稳定性和可靠性的应用。 Vishay Foil Resistors独特的超精密Bulk金属箔电阻器产品具有极低的电阻温度系数（TCR），并可在极端温度下实现出色的长期稳定性。

Vishay Foil Resistors产品系列包括各种电阻器配置和封装类型的产品，以满足各种应用的需求：表面贴装和通孔（引线）配置中的分立电阻器和电阻器网络;定制芯片电阻网络;精密微调电位器;和用于混合电路的分立芯片。

2000年，随着BulkMetal®Z-Foil的推出，Vishay Foil Resistors取得了技术突破。基于这项革命性技术的产品可提供0.2 ppm /°C的绝对温度系数（TCR）。 TCR越低，尽管环境温度变化并且在通电时自加热，电阻器仍能保持其精确值越好。块状金属箔电阻器基本上是无感的（小于0.08微亨利）并且不是电容性的，提供大约1纳秒的上升时间，使其特别适用于高频应用。此外，其热电动势小于0.05μV/°C，这对低电阻直流应用尤为重要。

凭借屡获殊荣的BulkMetal®箔电阻器，设计人员可以显着减少电路误差并大大提高整体电路性能。通过利用BulkMetal®技术的整体稳定性，高频性能和可靠性，Vishay Foil Resistors可以生产以客户为导向的产品，旨在满足具有挑战性的技术要求。

More than four and a half decades after its invention by physicist Dr. Felix Zandman in 1962, Bulk Metal® Foil (BMF) technology still outperforms all other resistor technologies available today for applications that require precision, stability, and reliability. Vishay Foil Resistors'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.

The Vishay Foil Resistors portfolio comprises products in a variety of resistor configurations and package types to meet the needs of a wide range of applications: discrete resistors and resistor networks in surface mount and through-hole (leaded) configurations; customized chip resistor networks; precision trimming potentiometers; and discrete chips for use in hybrid circuits.

In 2000, Vishay Foil Resistors achieved a technological breakthrough with the introduction of Bulk Metal® Z-Foil. Products built on this revolutionary technology deliver an absolute temperature coefficient of resistance (TCR) of 0.2 ppm/°C. The lower the TCR, the better a resistor can maintain its precise value despite ambient temperature variations and self-heating when power is applied. Bulk Metal Foil resistors are essentially non-inductive (less than 0.08 micro Henrys) and not capacitive, providing a rise time of about 1 nanosecond, making it particularly suitable for high frequency application. Furthermore, its thermal EMF is less than 0.05 µV/°C making it particularly important for low-ohmic DC applications.

With the award-winning Bulk Metal® Foil resistors, designers can significantly reduce circuit errors and greatly improve overall circuit performance. By taking advantage of the overall stability, high-frequency performance, and reliability of Bulk Metal® technology Vishay Foil Resistors can produce customer-oriented products designed to satisfy challenging technical requirements.
