Product Overview
The Bel Fuse SCS Series High Frequency SMD Current Sensing Transformers are surface mount components designed for non-invasive current detection in various applications. These transformers accurately sense current flow in power supply circuits, feedback control systems, safety and control circuits, and DC to DC converters/chargers. They offer a cost-effective, low-loss solution for measuring currents in high-frequency voltage regulators and switch-mode power supplies. Key features include very low DC resistance, automatic pick-and-place compatibility, and a wide operating temperature range.
