1053 Inductance Decade Box Data Sheet

Product catalog summary
Description: The Time Electronics 1053 Inductance Decade Box is a precision instrument designed for filter design, experimental use, general substitution, and DC to DC converter design. It is housed in a robust, fully screened metal case, making it suitable for both laboratory and field use. Inductance is adjustable via four dials, offering steps of 1 mH, 10 mH, 100 mH, and 1 H, with a maximum setting of 11.11 H. The unit uses custom wound, high permeability ferrite core inductors for stability and minimal external magnetic field influence.

1053 Inductance Decade Box Data Sheet-1

Time Electronics Description A precision decade inductance box suitable for filter design, experimental, general purpose substitution, and DC to DC converter design. The 1053 is housed in a fully screened robust metal case and is both compact and durable, making it ideal for laboratory or field use. Inductance is set by four easy-to-read dials that are divided into 4 decades, and 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. Safety Terminals: The front panel safety terminals are compatible with 4 mm shrouded plugs, as well as standard plugs, bare wires, and spade terminals. Features • 1 mH to 10 H • 3 % accuracy • High stability • In-line readout • Compact and robust design • Safety terminals • Fully screened Average resistance per step Due to continuous development Time Electronics reserves the right to change specifications without prior notice.
