Input Voltage Dividers for Digital Multimeters and Range-Switching Instruments
Introducing New Smaller Models at Lower Cost
The exceptional performance of this extensive family of
Type 1776 Precision Decade Resistor Voltage Dividers has
There are now 39 standard models in the expanded
family of Type 1776 precision resistor networks that include:

•3, 4, and 5 - decade voltage
dividers with ratios from 10:1 to
10,000:1.
•1,200 volts continuous ratings
and overvoltage to 2,000 volts.
•Many combinations of Ratio and

been achieved through the special
combination of advantages
provided by Caddock's Tetrinox®
resistance lms. This advanced
film resistor technology provides
the performance characteristics
required by the precision input
signal circuits of both bench-type
and laboratory digital instruments.
In addition to requiring less
board space, these compact
precision resistor networks deliver higher performance than
selected discrete resistor sets and thin-lm networks.

table)
Ratio Tolerance: Maximum
ratio error. (See the specific
Figures for the Ratio Denition).
Ratio Temperature Coefcient:
Maximum ratio TC error. (See
the specific Figures for the
Ratio Denition).
Range 1: -40°C to +85°C.
Range 2: 0°C to +70°C.
Voltage Coefficient of Ratio
(ppm/volt): R1 in series with any
combination of R2, R3, R4, and
R5, 100 volts to rated voltage.
Load Life: Ratio stability of
resistance under full load at
+70°C, rated voltage applied to
R1 in series with any combination
of R2, R3, R4, and R5 for 2000 hrs.
Shelf Stability of Ratio: Six
months at shelf conditions.
Overvoltage: Maximum
voltage of 1.67 times rated
DC voltage. Volts DC or peak
AC applied to R1 and any
combination of R2, R3, R4, and
R5 in series with R1 for 10
seconds.
Voltage Rating: DC or RMS
AC voltage applied to R1 in
series with any combination of
R2, R3, R4, and R5.
Storage Temperature: -40°C
to +85°C.
