Vishay Intertechnology, Inc. today announced the release of the VFCP series of ultra-high-precision, surface-mount Bulk Metal Z Foil resistors in a flip chip configuration that provides an outstanding power to size ratio. The five new VFCP resistors are the industry's first in a flip chip design to combine high power ratings up to 750 mW at 70 °C with long-term stability down to ±0.005 %, very low typical TCR of ±0.2 ppm/°C, excellent PCR of ±5 ppm typical at rated power, and tight tolerance of ±0.01 %.
These new resistors are designed for applications in which ultra-precise, ultra-stable, ultra-reliable resistors with an extremely low total error budget are required under load and extreme environmental conditions. The wide range of intended end products include automatic test equipment; high-precision instrumentation; laboratory, industrial, and medical equipment; high-end audio gear; electron beam scanning and recording equipment including electron microscopes; and military, space, airborne, and downhole instruments and communications systems. The 35 % space savings realized by using the VFCP series flip chip design over wrap-around designs enables more compact end products.
Vishay's revolutionary BMZF technology provides a significant reduction of the resistive component's sensitivity to ambient temperature variations and applied power changes . This breakthrough level of stability, more than an order of magnitude better than that offered by thin film technology, allows designers to guarantee a high degree of accuracy in fixed-resistor applications.
The VFCP series consists of resistors in five surface-mountable case sizes, 0805, 1206, 1506, 2010, and 2512, with a range of maximum power ratings from 100 mW to 750 mW and resistance ratings from 10 Ω to 150 kΩ, with even lower and higher resistance values available by request. The resistors achieve excellent load-life stability of ±0.01 % at maximum power, and even greater stability of ±0.005 % at decreased power. |
