VPG Military-Grade, Mission-Critical Resistors
Featured Product from New Yorker Electronics Co., Inc.
New Yorker Electronics has just released the VPG Foil Resistors new Model 303337 ultra-high precision military- and space-grade resistor. As one of the industry’s most precise and stable precision resistors, the Model 303337 offers high-performance current sensing within mission-critical applications.
The Model 303337 ultra-high precision surface mount resistor is suited for demanding military, aerospace, defense and space applications, including those where a precision resistor is required to quickly reach thermal equilibrium within circuits that either require fast response times or experience rapid current changes.
Within the military, aerospace, defense and space industries, typical applications include commercial and military avionics, switching linear power supplies, power amplifiers, power management systems, feedback circuits, measurement instrumentation and associated automatic test equipment. Other applications include precision high current-sensing and precision electronic scales. They provide enhanced characteristic capabilities resulting in superior performance when compared with other resistor technologies.
The custom-made resistors are available tolerances of: 0.1%, 0.2%, 0.25%, 0.5% and 1.0%, based on project need.
The Model 303337 produces a highly precise voltage that is directly proportional to measured current levels, with significantly reduced component sensitivity to applied power changes, including PCR and thermal resistance values. The industry-exclusive design of the Model 303337 incorporates VPG’s own proprietary Bulk Metal® Z Foil resistive technology, along with a four-terminal Kelvin connection, for ultra-high precision current sensing and temperature stability to 3W.
