Product Description
Product Overview
The Signal Transformer SCS Series is a new line of high-frequency Surface Mount Device (SMD) current sensing transformers designed for accurately detecting current flow in an application's conductor. These non-invasive components are ideal for use in power supply circuits, feedback control systems, safety and control circuits, and DC-to-DC converters and chargers. The SCS Series offers a cost-effective, low-loss method for measuring currents in high-frequency voltage regulators and switch-mode power supplies, featuring very low DC resistance and suitability for automatic pick-and-place assembly.Product Attributes
- Brand: Signal Transformer (belfuse.com/signal)
- Series: SCS Series
