Product Overview
The ARCS series shunt resistors are designed for high-current automotive applications, capable of handling hundreds to thousands of amperes. Featuring special alloy materials, they offer excellent long-term stability and can withstand pulse currents significantly higher than their rated current. Key advantages include low current coefficient, superior compensation characteristics, and very low thermal EMF (<0.5V/ to copper), ensuring minimal impact on voltage output. Their flat structure results in low inductance (<3nH), making them ideal for high-frequency applications.
