VI-J3Y-EW-F1 Description

Short technical summary and product information.

The Vicor VI-J3Y-EW-F1 is an isolated DC-DC converter from the VI-J00 MiniMod family. It provides a single regulated output of 3.3V at 20A, delivering 66W of power. The module operates from a nominal 42V input and features overcurrent protection (OCP) and short-circuit protection (SCP).

 

With an efficiency of 88%, the converter is designed for commercial ITE (Information Technology Equipment) applications. It is housed in a half brick package measuring 57.9mm x 47.2mm x 20.1mm and uses through-hole mounting for reliable board attachment.

 

The operating temperature range is -10°C to 100°C, making it suitable for a variety of industrial environments. The VI-J00 series utilizes Vicor's zero-current-switching (ZCS) architecture for low noise and high reliability.
