Signal SCS Series High Frequency SMD Current Sensing Transformers

Product Overview

The Signal SCS Series offers a new line of high-frequency Surface Mount Device (SMD) current sensing transformers. These components are designed for non-invasive detection of current flow in application conductors, providing accurate current sensing in power supply circuits, safety circuits, and control circuits. They are a cost-effective, low-loss solution for measuring currents in high-frequency voltage regulators and switch-mode power supplies. Applications include feedback control, load drop/shutdown protection, safety/control circuits, and DC-to-DC converters/chargers.
