1. The 3.5-R Series Bel Fuse is a range of high-performance, PC board-mountable micro-transformers with a planar structure. This series is designed for use in power supplies, switching and EMI filter circuits, and other power management applications.
2. The 3.5-R Series is available in various power ratings, from 0.1 VA to 20 VA, and offers a low profile height of 7.0 mm or lower. It also has a small size that enables it to be mounted in small spaces.
3. These transformers are available in two winding configurations: single and double. The single configuration is suitable for applications requiring isolation and/or galvanic noise filtering, while the double is used for high reliability applications requiring additional turns ratio adjustments.
4. The 3.5-R Series features a high insulation rating that ensures noise rejection and electrical isolation between primary and secondary windings, even when using a common mode noise filter.
5. This series is UL approved, RoHS compliant, and also meets EN 60950, CE, and IEC requirements. It is ideal for applications where noise immunity and high reliability and performance are a must.
