Temperaturabhngigkeit des elektrischen Widerstandes von
MANGANIN-Widerstnden
temperature dependence of the electrical resistance of
MANGANIN-resistors
The Resistor type A-H with its isolated 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 low inductance. The low
thermal resistance to the aluminum base plate of < 3 K/W
permits loading up to 10 W with only little self-heating.
Remarks:
- please note that the above standard values are available
- Tolerance 0.1% for values from 5 mOhm
