Mission-critical foil resistors are military-grade

VPG Model 303337 Foil Resistors are ultra-high precision military and space-grade, delivering high-performance current sensing within mission-critical applications. Device are suitable to designs such as when a precision resistor is required to quickly reach thermal equilibrium in circuits either requiring fast response times or experiencing rapid current changes. Other applications include precision high current-sensing and precision electronic scales. Devices provide enhanced characteristic capabilities resulting in enhanced performance when compared with competing technologies. The custom-made resistors are available in tolerances of: 0.1%, 0.2%, 0.25%, 0.5% and 1.0%, based on project need.
