Token Voltage RY31A High Frequency Resistors are rugged resistor designed to sustain the very high peak power and current inputs generated by capacitor banks, pulse generator systems, and steady state current loads. Their linear response over a broad bandpass provides an accurate indication of current magnitude free from inductive components. Inherent in RY31A Resistor design is a coupling between the major electrical parameters of resistance, bandpass, energy capacity, and wattage rating. frequency resistors

This interdependence led TOKEN to provide an improved series of standard units covering a broad range of specifications. RY31A resistor is produced by depositing a metal oxide film on a high-grade ceramic body and coated with a lacquer, which provides electrical, mechanical and climatic protection. High Frequency RY31A Resistors features higher thermal resistance and larger electric power capacity for the compact volume.

RY31A Resistors are ideal for: SCR Current Measurements, Current Control of Automatic Welders, Measure Output of Automotive Alternators, Fault Current Detection to Determine Bearing Wear of Stem Turbine Generators, EBW Testing, Current Detection in Detonation Systems, Three-Phase Fault Testing in Power Transmission Substations, Fault Detection in Modulators, Measurement of Laser System Currents, Chopper Current Control in Electric Cars, and Circuit Breaker Testing.

For having extensive experience in surge discharge circuitry, we will be happy to supply additional information on your specific needs.For additional technical specifications and price information, please direct your inquiries to Token Sales Team.
