Decade Resistors

DB62 Series

Page 1 of 1

The DB62 Series oers 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. Aer

inhering the DB62 series from esi,

IET used its own resistance tech-

nology to signicantly improve the

stability of the unit.

Features:

• Four available models

• High accuracy: ±(0.01% + 2 mΩ)

• Serves DC through audio frequency

applicaons
