The General Radio 1482-F Standard Inductor was introduced in Catalog N (1954) and remained available through Catalog U (1970).
The Type 1482-F is 2 mH inductance standard designed to replace the Type 106 Standard Inductor. The inductor is symmetrically wound toroid on a ceramic core. The toroid is hermetically sealed in a mixture of cork and silica gel then potted in an aluminum case. The connections to the inductor are three Type 938-A jack-top binding posts. Two of the terminals for the inductor and the third is the case connection with shorting link, affording two or three terminal standards. Each inductor is supplied with a calibration certificate with corrections for 200 Hz, 500 Hz, and 1 kHz and actual specifications.
For all the members of the series see 1482 article.
