Licensed Options **  ISO 9001 and ISO 14001 certified manufacturing facilities  Output OCP/OVP auto restart  Compliant to IPC-9592A, Category 2, Class II  Shorter pins  Unthreaded heatsink holes  Tunable Loop* for transient response optimization Description The JRCW016A0R Orca series of dc-dc converters are a new generation of isolated, very high efficiency DC/DC power modules providing up to up to 16Adc output current at a nominal output voltage of 28Vdc in an industry standard, DOSA compliant half- brick size footprint, which makes it an ideal choice for high voltage and high power applications. Threaded-through holes are provided to allow easy mounting or addition of a heatsink for high-temperature applications. The output is fully isolated from the input, allowing versatile polarity configurations and grounding connections. This module contains an optional new feature, the Tunable Loop, that allows the user to optimize the dynamic response of the converter to match the load with reduced amount of output capacitance, leading to savings on cost and PWB area. * Trademark of General Electric Company # UL is a registered trademark of Underwriters Laboratories, Inc. † CSA is a registered trademark of Canadian Standards Association. ‡ VDE is a trademark of Verband Deutscher Elektrotechniker e.V. ** ISO is a registered trademark of the International Organization of Standards March 23, 2016 ©2016 General Electric Company.

These are absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the device reliability.

An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple standalone operation to being an integrated part of complex power architecture. To preserve maximum flexibility, internal fusing is not included. Always use an input line fuse, to achieve maximum safety and system protection. The safety agencies require a time-delay or fast-acting fuse with a maximum rating of 25 A in the ungrounded input connection (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information. March 23, 2016 ©2016 General Electric Company. All rights reserved.
