The General Radio 1481-G Inductor was introduced in Catalog M (1951) and remained available through Catalog R (1963).
The Type 1481-G inductor is of the toroid wound, dust-core design. The toroid is clamped between the two aluminum case halves. The 1481-G inductor is derived from Types 940 and 1490 decade inductors. Each inductor is engraved with nominal inductance, accuracy, and inductance change versus current. The connections are Type 938-B Jack-Top binding posts, one being grounded.
See the overview page 1481 for the complete series.
Specifications
- Nominal Inductance: 100 mH
