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
