1053 Inductance Decade Box

• 1mH to 10H

• 3% accuracy

• High stability

• In-line readout

• Compact and robust design

• Safety terminals

• Fully screened

DESCRIPTION

A precision decade inductance box suitable for lter 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 eld use.

Inductance is set by four easy-to-read dials that are divided into 4 decades, and provide 1mH, 10mH, 100mH, and
1H steps. The maximum setting is 11.11H.

It is custom wound and high permeability ferrite cores ensure insignicant inuence from external magnetic elds and
maximum stability.

Safety Terminals: The front panel safety terminals are compatible with 4mm shrouded plugs, as well as standard plugs,

bare wires, and spade terminals.
