Decade Resistors

DB62 Series

The DB62 Series oers a depend­able, long-term service in preci­sion dc through audio frequency
applications. The units feature
6 decades with non-inductive,
precision resistors mounted in a
low-noise, shielded housing. Aer
inhering the DB62 series from esi,
IET used its own resistance tech­nology to signicantly improve the
stability of the unit.
