Current Sense Resistors

Littelfuse Current Sense Resistors provide an optimal solution for measuring current flow to provide control and overcurrent protection. These resistors feature AEC-Q200-compliant models, surface-mount designs, and high-current options. Suitable applications include power management, servers, and low ESL environments. Littelfuse Current Sense Resistors are designed to exhibit excellent performance in noise suppression, resistance, and surface heat distribution.
