Vishay Intertechnology Expands Power Transformer Portfolio With New IFBT Series
Vishay Intertechnology has expanded its power transformer portfolio with the new Vishay Dale IFBT series, specifically designed for flyback converter topologies. This series comprises 17 customizable, surface-mount flyback transformers, enhancing Vishay's offerings for various power conversion applications.
The IFBT series is engineered to operate efficiently with a wide input voltage range of 26 V to 72 V, at an operating frequency of 250 kHz. A key differentiator is its high isolation capability, providing 1500 VRMS for 60 seconds between the primary and bias windings and the secondary winding, ensuring robust safety and reliability in demanding environments.
These transformers feature multiple windings, offering design flexibility through combinations of series and parallel connections. This adaptability allows the devices to support a broad spectrum of output voltages, from 1.8 V to 24 V, and output currents ranging from 0.5 A to 9.0 A. Furthermore, their open construction makes it easy to modify windings to meet specific customer requirements, making them highly versatile for custom solutions.
