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.
