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 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 1mH, 10mH, 100mH, and
1H steps. The maximum setting is 11.11H.
It is custom wound and high permeability ferrite cores ensure insignificant influence from external magnetic fields 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.
