Vishay Intertechnology has expanded its power transformer portfolio with the release of the Vishay Dale IFBT series, a line of 17 customizable, surface-mount flyback transformers designed to support a wide 26 V to 72 V input range, 250 kHz operation, and a high isolation of 1500 VRMS for 60 seconds.
Vishay Intertechnology, Inc. announced the rollout of its new component lineup, bringing surface-mount flexibility to flyback converter topologies. The company is offering samples and production quantities now, though buyers should expect lead times ranging from 10 to 12 weeks.
Core Specifications and Winding Flexibility of the Vishay Dale IFBT Series
The 17 devices making up the Vishay Dale IFBT series feature inductance values ranging from 35.0 µH to 75.0 µH. Designed to function efficiently at an operating temperature range of -40 °C to +125 °C, these RoHS-compliant components utilize multiple windings. This configuration allows engineers to deploy series and parallel connection combinations tailored to specific voltage and current handling requirements.
By combining this winding flexibility with a wide input voltage range, the transformers achieve output voltages spanning from 1.8 V to 24 V alongside output currents from 0.5 A to 9.0 A. Furthermore, the open construction of the parts allows for straightforward modification of the windings when custom customer requirements demand it.
Target Applications in PoE Designs and Industrial Automation
The IFBT series is built to serve in several distinct power delivery roles. According to the company announcement, the components act as flyback transformers for 6 W and 30 W Power over Ethernet (PoE) designs, as well as powering isolated DC/DC converters up to 30 W.
Beyond telecommunications and PoE systems, typical deployment scenarios span a broad cross-section of heavy industry and consumer technology.
- Automotive lighting LED driver transformers
- Energy generation, distribution, and management systems
- Industrial drives, tools, and automation systems
- Home and building controls, consumer devices, and white goods
- Telecom equipment and medical instrumentation
