***  Note  these inductance standards may be decades old and no longer fall within the original specifications for accuracy.  For best accuracy, we recommend having them charted for actual value and using the charted value instead of the nominal value.  Feel free to contact our sales team for further information on any specific inductor value.***

The GenRad 1482 Standard Inductors are the standard of choice in metrology labs. Used today by national metrology institutes and primary standards bodies around the world, these inductors have no peer or equivalent.

 

IET continues to produce the 1482 standard inductors to the same exacting specs as General Radio. These standard inductors are accurate, highly stable standards of self inductance for use as a low frequency reference of working standard in the laboratory.

 

Records extending over 30 years, including those of standard inductors that traveled to national laboratories in several countries for calibration, show long-term stability well within ±0.01%.

 

Each standard inductor is a uniformly wound toroid on a ceramic core. It has a negligible external magnetic field and hence essentially no pickup from external fields. The inductor is resiliently supported in a mixture of ground cork and silica gel, after which the whole assembly is cast with potting compound into a cubical aluminum case.

 

Sizes of 500 µH and above have three terminals, two for the inductor leads and the third connected to the case, to provide either a two- or three terminal standard. The 50-, 100-, and 200 µH sizes have three additional terminals for the switching used to minimize connection errors.
