When failure is not an option, turn to VPG Foil Resistors for applications where performance is a high priority. Our solutions are successfully employed in many environments that demand performance, quality and reliability
The demands of the aerospace and commercial segments differ in one major area — ongoing reliability. In some cases there is only one chance to complete the mission, and the system cannot be brought back into the shop for repairs. For example, some systems are in transit through deep space for 10 years or more before being activated. It is critical that every component activates when required and performs flawlessly throughout the mission. That’s why VPG Foil Resistors Bulk Metal® Foil precision resistors, with their long-term consistency and reliability, are the only choice for aerospace applications.
In audio systems, "high end" means a faithful reproduction of the original signal and the absence of noise insertion by the electronic components, particularly resistors. The audio discrimination level is sometimes beyond the capabilities of measuring instruments, but nonetheless aurally detectable. VPG Foil Resistors Bulk Metal® Foil precision resistors offer the lowest noise available and are essential components of any high-end audio system.
Automatic test equipment (ATE) performs at high speeds, reading and recording information from thousands of devices/boards that would otherwise need to be probed by hand. Any introduction of spurious signals from the ATE machine or its components could result in the failure to reject a faulty device, or conversely, cause the rejection of perfectly good products. If ever there was a place not to be "penny wise and pound foolish" it is in the resistor of an ATE. The wisest choice is Bulk Metal® Foil precision resistors from VPG Foil Resistors.
The electronics used in commercial avionics are exposed to dramatic temperature excursions, shock and vibration, moisture, and the test of time. In engine, cabin, and flight control applications, resistors need to maintain their values despite all of these factors. VPG Foil Resistors Bulk Metal® Foil precision resistors have a long history of delivering high performance for applications in commercial aviation, supported by more than 30 years of load-life testing.
Energy and smart grid applications present some of Earth’s most rugged environments for electronic components. VPG Foil Resistors products for solar and wind turbine power systems provide the high reliability and long life required by solar energy cells and panels, smart meters, solar and wind inverter circuits, wind turbine braking circuits, hybrid electric vehicles, and more. VPG Foil Resistors provides special engineering consulting, test, and assessment services for precision resistor applications in the energy sector. Analog circuits are among the building blocks of many key assets
Industrial systems sometimes favor cost-savings over quality when it comes to electronic components, but when all factors are taken into consideration, quality resistors turn out to be the least expensive solution. In the long run, a reliable and stable resistor costs less than one that must be replaced or that requires additional circuitry to compensate for lack of precision. Factor in warranty repair expenses, downtime in the hands of the customer, and transportation costs for repairs, and the "savings" from using second-best resistors quickly disappear. Even when an assumed or measured returns rate is applied, VPG Foil Resistors Bulk Metal® Foil precision resistors turn out to be the most economical solutions.
In lab and metrology applications, the only appropriate resistors are those that will retain their initial value over time. Hermetic packaging is a must since every laboratory will have some humidity fluctuations. Additional essentials include stability under temperature fluctuations, absence of thermally active junctions, and a low temperature coefficient of resistance. All of these criteria are met by VPG Foil Resistors Bulk Metal® Foil precision resistors.
Accurate and stable instrumentation in the medical field requires the ability to detect very small signals without producing false readings. For the complement of resistors surrounding the operational amplifier, and anywhere else resistors are needed in medical applications, the device of choice is the VPG Foil Resistors Bulk Metal® Foil precision resistor.
VPG Foil Resistors Bulk Metal® Foil precision resistors have been used for more than 40 years in military equipment — even before a suitable MIL spec was created. In the late 1960s, MIL R 55182 was established and the RNC90 style was applied to Bulk Metal Foil resistors. Testing to an “R” failure rate was conducted and the devices have been used continuously ever since. Today, the resistors are serving in every category of military equipment that relies on electronics for its functionality.

Whether they’re used in the guidance system of a cruise missile, the autopilot of an airplane, or the remote responder of a weather station, VPG Foil Resistors Bulk Metal® Foil precision resistors are consistently the best choice for precision instrumentation because of their initial accuracy and long-term stability.
