The L4CA Series from Littelfuse are Four Terminal Current Sense Power Resistors designed for power management and low ESL (equivalent series inductance) applications. They have a resistance as low as 0.5 milli-ohms, a resistance tolerance of ±1% and a power rating of 1 W. These compact chip resistors are fabricated using ceramic substrate and have separate voltage sensing terminals. They exhibit excellent performance in resistance, noise performance, and surface heat distribution, and have a lower surface temperature. These RoHS-compliant high-voltage resistors are available in surface-mount packages.
