Introduction of Advanced 150 W Planar Transformers
Vishay Intertechnology, Inc. has recently introduced a remarkable series of low profile, space-grade planar transformers that are setting new standards in the industry. These 150 W transformers, optimized specifically for 28 V input forward converters, are the first of their type designed for applications in avionics, military, and space environments. With a focus on reduced costs, compactness, and enhanced power density, these transformers are designed to meet and exceed the requirements of various rigorous standards.
Key Features and Benefits of SGTPL-28 Series
One of the standout features of the SGTPL-28 series is its ability to provide significant benefits over traditional planar transformers. These innovations include improved winding fill, which allows the transformers to occupy much less PCB space without sacrificing performance. As a result, designers can achieve greater efficiency and power density, which are crucial in today’s advanced electronic systems. With input voltage capabilities ranging from 18 V to 36 V, these transformers also come equipped with a robust dielectric withstand voltage of 1250 VDC and minimal leakage inductance.
Adaptability to Various Applications
The versatility of these transformers extends to their application in high reliability switch mode power supplies and various types of forward converters. This adaptability is further enhanced by the option for multiple secondary windings, allowing for the powering of two 12 V channels or up to four 5 V channels from a single transformer. This multifunctionality makes these devices an attractive choice for engineers looking to optimize performance in their designs.
Durability for Harsh Environments
In military and aerospace applications, durability is paramount. The new transformers are built to withstand the harsh conditions often encountered in these fields, featuring over-molded windings and high-temperature operation capabilities reaching up to +130 °C. These devices are rigorously tested to endure numerous thermal cycles as well as high levels of mechanical shock and vibration, exceeding the necessary qualifications.
Screening Options to Meet Diverse Needs
Responding to the diverse needs of the market, Vishay provides multiple screening options for the SGTPL-28 series. These include P-level screening designed for validation testing, L-level screening for low Earth orbit applications, and MIL-STD-981 screenings to ensure compliance with the highest standards of reliability. This range of options further emphasizes Vishay's commitment to meeting the specific requirements of each project in which their transformers are utilized.
Availability and Production Information
Samples and production quantities of the SGTPL-28 transformers are currently available, with lead times optimized for customer convenience. Typically, customers can expect delivery within eight weeks for P-level screening, 12 weeks for L-level screening, 16 weeks for B-level, and 26 weeks for S-level screening. This efficiency in supply chain management allows engineers to receive the components they need without extended delays.
