Ohmite’s Four Terminal Bare
Element Resistors provide
ultra low resistance values (to
0.0005Ω) for relatively high
current requirements, with
the advantages of a Kelvin
configuration and PC Board
mounting capability.
These shunt resistors are
specifically designed for low
resistance applications requir-
ing the highest accuracy and
temperature stability. This
Four Terminal version of
F E A T U R E S
• Ideal for current sensing applica-
tions
• 1% tolerance standard, others
available
• Low inductance (non-inductive
below 0.05Ω)
60 Series
Four Terminal Bare Element
610 Series (1 watt)

Ohmite’s 60 Series Resistor is
specially designed for use in a
Kelvin configuration, in which
a current is applied through
two opposite terminals and
sensing voltage is measured
across the other two terminals.
The Kelvin configuration
enables the resistance and
temperature coefficient of the
terminals to be effectively
eliminated. The four terminal
design also results in a lower
Temperature Coefficient of
Resistance and lower self
heating drift which may be
experienced on two terminal
resistors. The requirement
to connect to the terminals
at precise test points is elimi-
nated, allowing for tighter toler-
ancing on the end application.
