Single Decade HARS-X Unit
SINGLE DECADE UNITS
ORDERING INFORMATION
Single-decade units are available with
resistance as low as 1 m
Ω
per step to
as high as 10 M
Ω
per step. These units
satisfy many system applications re-
quiring only a single decade while
maintaining all the quality features of
the HARS series.
Each decade is enclosed in an alumi-
num case which can serve as a shield.
It may be panel mounted and inte-
grated with additional units to form
potentiometer circuits or other con-
figurations.
Each unit consists of low-inductance
resistors in series, with a high-perfor-
mance solid-silver-alloy-contact
switch.
* For less exacting applications, more economical tolerances are available:
- use "A" for "X" in part number for 0.05% basic accuracy, in lieu of .01%
- use "Q" for "X" in part number for 0.02% basic accuracy, in lieu of .01%
- use "B" for "X" in part number for 0.1% basic accuracy, in lieu of .01%
OPTIONS
- RM Rack mountable case for standard 19" rack
- K Kelvin type 4-terminal binding posts
- RO Rear output binding posts
