Bel Fuse SCS 2080 Transformer for Surface Mount Current Sensing in High Frequency Voltage Regulators
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.
