High Power Shunt Automotive Grade Current Shunt Resistor
High Power Shunts
A current shunt, also known as a current sense resistor or current-sensing resistor, is a type of resistor specifically designed to measure or monitor the current flowing through a circuit. It is typically a low resistance value resistor connected in series with the load or the circuit being monitored.
The current shunt works based on Ohm's Law, which states that the voltage across a resistor is directly proportional to the current flowing through it. By measuring the voltage drop across the shunt resistor, the current flowing through the circuit can be determined using Ohm's Law (I = V/R).
Current shunts are commonly used in various applications such as power electronics, battery management systems, motor control, and industrial automation. They provide an accurate and reliable method of current measurement, allowing for monitoring and control of the current levels in a circuit.

High power shunts are specialized resistors designed to handle high currents and provide precise current measurement. Here are some key features and applications:
1. Construction: They are typically made using a metal alloy element that is electron-beam welded to tinned copper terminals
2. Resistance Values: These shunts can have resistance values as low as 50 µΩ, which helps in achieving low voltage drops and high accuracy
3. Power Handling: They can handle high currents up to 1000 A and have permanent power ratings of up to 50 W
4. Temperature Coefficient: They have a low temperature coefficient (TCR) of 50 ppm/°C, ensuring stability across a wide temperature range
5. Applications: High power shunts are commonly used in battery management systems, automotive applications, and power monitorin
