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 (<3nH), they are ideal for high-frequency applications and ensure minimal impact on millivolt-level voltage outputs. These precision shunt resistors are crucial for accurate current sensing in demanding environments.
