A precision decade inductance box suitable for filter design, general purpose substitution, DC to DC converter design and calibration of measuring instruments.
The 1053 is housed in a fully screened robust metal case making it durable and compact. It is a practical instrument that is simple operation, suitable for use in electronics, production, R&D, or as a calibration tool in the lab or field.
Inductance is set by four easy-to-read dials that are divided into 4 decades. These provide 1 mH, 10 mH, 100 mH, and 1 H steps. The maximum setting is 11.11 H.
The unit features custom wound, high permeability ferrite core inductors that ensure insignificant influence from external magnetic fields and maximum stability.

Robust and portable
Inductance is selected by dialling the value required using the rotary switches. This enables precise setting with a clear unambiguous indication.
Each decade is scaled from 0 to 11. This allows a convenient overlap of the set values.
The 1053 connections are via safety terminals that are compatible with standard plugs, 4 mm shrouded plugs, bare wires, and spade terminals.
These terminals are specifically designed with safety features including limited opening distance and a raised flange around the metal connection surface. This ensures that the clearances are sufficient to make the exposed metal parts touch-proof.
