General Radio 1482R Features:

  • Stable within ±0.01%
  • Low, known temperature coefficient
  • Minimized connection errors
  • Toroidal--free from external fields

The 1482R Standard Inductor is an accurate, highly stable standard of self inductance for use as a low-frequency reference or working standard in the laboratory. Records extending over 13 years, including those of inductors that traveled to national laboratories in several countries for calibration, show long-term stabilities well within ±0.01%. It is a uniformly wound toroid on a ceramic core. It has a negligible external magnetic field and hence essentially no pickup from external fields.
