Product Description
Product Overview
The Bel Fuse SCS Series High Frequency SMD Current Sensing Transformers are a new line of surface mount components designed for accurately detecting current flow in application conductors. They offer a non-invasive method for sensing current in power supply circuits, safety circuits, and control circuits. These transformers are ideal for applications such as feedback control, load drop/shutdown protection, safety/control circuits, and DC to DC converters/chargers. They provide a cost-effective, low-loss solution for measuring currents in high-frequency voltage regulators and switch-mode power supplies.Product Attributes
- Brand: Bel Fuse (Signal Transformer)
- Technology: Surface Mount Technology (SMT)
- Core Material: EE Core
- Compliance: RoHS Compliant
- Customization: Custom versions available upon request
