WRL-L4
4 Terminal Symmetrical Footprint Current Sense Resistors
Our WRL-L4 series features a 4 terminal Kelvin sense metal foil resistor with precise tolerance and TCR on a standard footprint. Crafted from a unique nickel-copper alloy, its resistive foil element resists environmental factors, boasting anti-corrosion and anti-sulfur properties. Its innovative bottom-side design minimizes terminal parasitic effects, ensuring superior accuracy over top-side competitors. These resistors excel in automotive, battery pack, and challenging environment applications.
