New Yorker Electronics has released the newVPG Foil Resistors Model 303337 ultra-high precision military- andspace-grade resistor. As one of the industry’s most precise and stableprecision resistors, the Model 303337 offers high-performance currentsensing within mission-critical applications.
The Model 303337 surface mount resistor is suited for demanding
military, aerospace, defense and space applications, 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.
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(R) Z Foil resistive technology, along with a
four-terminal Kelvin connection, for ultra-high precision current
sensing and temperature stability to 3W.
