Ultra-Precision Shunt Resistor

(

)

40 Watts

Features

• Excellent temperature characteristics created by metal foil technology

• Accurate value on four-terminal wiring, even in low extremity of resistance

• High heat dissipation due to aluminum-clad construction with fins

• Readiness to mount to heat sink or water-cooled radiator

• Availability of threaded holes to fix cables with screw

Applications

PSB

• Current-sensing in precise power supply, motor driver, etc

*Thermal resistance of the heat sink 1°C/W.

Resistance value in ohm is expressed by a series of four significant digits and

an R designating the decimal point.

Available to use higher rated power with elevation of cooking effect.

Please keep temperature of surface less than 60°C.
