The ESTW010A0B provides 12Vdc nominal output voltage rated for 10A output current. The module incorporates GE’s vast heritage for reliability and quality, while also dc using the latest in technology, and component and process standardization to achieve highly competitive cost. The open frame module construction, available in both surface-mount and through-hole packaging, enable designers to develop cost and space efficient solutions. The module achieves typical full load efficiency greater than 90% at VIN=48Vdc. Standard features include remote On/Off, remote sense, output voltage adjustment, overvoltage, overcurrent and overtemperature protection. An optional heat plate allows for external standard, eighth-brick or quarter-brickheat sink attachment to achieve higher output current in high temperature applications. * Trademark of General Electric Corporation. # 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. § This product is intended for integration into end-user equipment .

To preserve maximum flexibility, internal fusing is not included, however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 15 A (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.

These sealed these instructions may result in the failure of or cause packages should not be broken until time of use. Once the damage to the modules, and can adversely affect long-term original package is broken, the floor life of the product at reliability. conditions of  30°C and 60% relative humidity varies according to the MSL rating (see J-STD-033A). The shelf life In a conventional Tin/Lead (Sn/Pb) solder process peak for dry packed SMT packages is a minimum of 12 months ° reflow temperatures are limited to less than 235 C. from the bag seal date, when stored at the following ° Typically, the eutectic solder melts at 183 C, wets the land, conditions: < 40° C, < 90% relative humidity. and subsequently wicks the device connection. Sufficient Pick and Place time must be allowed to fuse the plating on the connection to ensure a reliablesolder joint. There are several types of The ESTW010A0B modules use an open frame construction SMT reflow technologies currently used in the industry. and are designed for a fully automated assembly process. These surface mount power modules can be reliably The modules are fitted with a label designed to provide a soldered using natural forced convection, IR (radiant large surface area for pick and place operations. The label infrared), or a combination of convection/IR. For reliable meets all the requirements for surface mount processing, as soldering the solder reflow profile should be established by well as safety standards, and is able to withstand reflow accurately measuring the modules CP connector o temperatures of up to 300 C. The label also carries product temperatures. information such as product code, serial number and the Lead Free Soldering location of manufacture. The –Z version of the ESTW010A0B modules are lead-free (Pb-free) and RoHS compliant and are both forward and backward compatible in a Pb-free and a SnPb soldering process. Failure to observe the instructions below may result in the failure of or cause damage to the modules and can adversely affect long-term reliability. August 26, 2016 ©2014 General Electric Company.

Post Solder Cleaning and Drying Considerations Post solder cleaning is usually the final circuit-board assembly process prior to electrical board testing. The result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly.
