Resistor type
A-N
with its separated current and voltage
connections configured as a four-terminal resistor (i.e.,
Kelvin connection) is ideally suited for precise current
measurement, current limitation or regulation in power
units, current sources, and electronic loads. It is also
applied for current measurements in pulse width modulated
(PWM) control circuits for inductive users such as servo
and stepper motors and solenoid driver circuits.
Design in foil technique and application of precision
resistance alloy
MANGANIN
warrants for a long term
stability. By optimization of the shape, a high load capacity
was obtained while maintaining accuracy and small
inductance.
