Component Specifications

Definition
A reference resistor network is a precision electronic component consisting of multiple high-stability resistors arranged in a specific configuration, designed to provide accurate and stable resistance values for calibration purposes in resistance measurement circuits. It serves as a primary standard for comparing unknown resistances, ensuring measurement traceability to international standards.
Working Principle
Operates based on Ohm's Law (V=IR), providing known resistance values against which unknown resistances are compared. The network maintains exceptional stability through temperature compensation, low thermal EMF, and minimal drift characteristics. In measurement circuits, it creates precise voltage dividers or current paths that enable accurate resistance calculations through comparison methods.
Materials
High-purity metal alloy resistors (typically nickel-chromium or manganin), ceramic substrate, gold-plated copper terminals, epoxy encapsulation, temperature compensation elements.
Technical Parameters
  • Stability ±25ppm/year
  • Tolerance ±0.01% to ±0.1%
  • Power Rating 0.1W to 1W
