DB877 Decabox. Coaxial decade resistance box
DB877 is a coaxial decade resistance box, which provides 0.1Ω to 12MΩ of resistance.
It features eight decades made up of precision wire-wound resistors.
The DB877 is designed to provide long-term dependable service in precision DC and audio frequency applications. Two sets of four dials each are configured so that the operator can easily switch in the exact resistance. Up to 120 million divisions of resolution are provided to obtain the closest possible resistance value.

• ± (0.01% + 7mΩ) Initial Accuracy

• ± (0.02% + 10mΩ) Long-term Accuracy

• Low Temperature and Power Coefficient

• Extruded Metal Case for Shielding and Mechanical Protection

• Solid Silver Alloy Switch Contacts to improve repeatability to 1mΩ

APPLICATIONS: Used to dial in exact resistance values for DC and Audio frequency ranges.
