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)

• RoHS compliant

• Radial, self-supporting, design is

ideal for PC board mounting

• High Power-to-size ratio

• Decimal marked, silicone coated

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.
