Durable automotive shunt resistor RESI ARCS6918FL100A9 with special heat treatment process and excellent stability
Product Overview
The ARCS series shunt resistors are designed for automotive applications, capable of handling currents from 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. The ARCS series boasts a low current coefficient and superior compensation characteristics due to a special heat treatment process. With a low thermal EMF of less than 0.5V/ to copper and low inductance (
