The Bel Fuse SCS series represents a new line of high-frequency surface mount current sensing transformers designed for operating frequencies from 50kHz to 1MHz. These compact and cost-effective transformers accurately sense current flow in applications up to 15A through a non-invasive method. They are ideal for use in power supply circuits, feedback control, safety and control circuits, and DC-DC converters/chargers, offering a low-loss approach to current measurement in high-frequency voltage regulators and switch-mode power supplies. The SCS series is available in three EE core sizes: SCS4.4, SCS4.6, and SCS8.3, featuring the smallest footprint and most compact size on the market.
| Specification | Details |
|---|---|
| EE Core Sizes | 4.4 mm (SCS4.4), 4.6 mm (SCS4.6), 8.3 mm (SCS8.3) |
| Operating Frequency | 50 kHz to 1 MHz |
| Primary Rated Sensed Current | 7 A (SCS4.4), 9 A (SCS4.6), 15 A (SCS8.3) |
| Temperature Rise | Less than 35C (SCS4.4), 40C (SCS4.6) above 25C ambient for primary current. Higher current causes increased rise. |
| Operating Temperature Range | -40 C to +125 C |
