Decade Resistors
DB62 Series
Page 1 of 1
The DB62 Series offers a depend-
able, long-term service in preci-
sion dc through audio frequency
applications. The units feature
6 decades with non-inductive,
precision resistors mounted in a
low-noise, shielded housing. After
inheriting the DB62 series from esi,
IET used its own resistance tech-
nology to significantly improve the
stability of the unit.
Features:
• Four available models
• High accuracy: ±(0.01% + 2 mΩ)
• Serves DC through audio frequency
applications
