This document describes shunt resistors for energy meters. Key points: - The resistors have extremely low resistance values (<0.5nH), negligible temperature coefficients, and can dissipate up to 5W of power. - They are designed for precision current sensing applications like energy meters, bus bars, welding equipment, and battery chargers. - The resistors have high temperature and pulse power ratings and come in various resistance values with tight tolerances.

1. • 4-Terminal (Kelvin) connection design.
•Extremely low resistance values.
•Very low inductance (<0.5nH)
• Negligible EMF (3μ V/°C)
