Before dissecting the datasheet, it is vital to understand the component itself. The EN3660 is typically categorized as a high-performance, non-isolated DC-DC power module. Manufactured to meet the rigorous demands of modern electronics, it functions as a step-down (buck) converter, translating higher voltage inputs into stable, lower voltage outputs required by sensitive microprocessors, FPGAs, and ASICs.
The datasheet will provide a graph of maximum output current vs. ambient temperature. This is your design boundary.
: Various sub-series often denoting specific shell sizes (ranging from 8 to 25) and entry sizes. en3660 datasheet
: Designed to mate with specific aerospace connectors such as MIL-DTL-38999 (Series III and IV), and Temperature Classes
The EN3660 standard is divided into multiple parts, each acting as a standalone product standard for a specific accessory: EN3660-001 : Technical specification (general requirements). EN3660-002 : List of product standards and compatible connectors. EN3660-003 : Grommet nuts. EN3660-062 to 066 Before dissecting the datasheet, it is vital to
This section includes detailed drawings of shell sizes (from size 9 to 25), insert arrangements, and keying positions. Key parameters to look for:
The "EN" prefix often denotes a series of efficient, high-density power solutions, while "3660" usually refers to specific electrical characteristics, such as input voltage range or output current capabilities. In the context of power modules similar to this designation, users can generally expect an input range accommodating 36V to 60V inputs, making it ideal for telecom and industrial power buses. The datasheet will provide a graph of maximum
This section is often the most misunderstood. Beginners see numbers like “Input voltage: 40V” and think, “Great, I’ll run it at 39V.” But the absolute maximum rating is not a recommended operating condition; it is the threshold beyond which permanent damage occurs. For the EN3660, the table might show:
It is possible that:
Finally, the datasheet tells you how to buy the EN3660. Example:
