  • EFB0512MA -F00 ZP MM 1313T Part Number Breakdown:
    • 'EFB' Delta product series designation (Slimline, high-efficiency axial DC brushless fan).
    • '05' Frame size code representing 50mm x 50mm
    • '12' Rated voltage operating at 12V DC (Operational range: 7.0V to 13.8V).
    • 'M' Medium speed classification (relative to low "L" or high "H" variants).
    • 'A' Generation / Mechanical design profile thickness classification (10mm depth)
    • '-F00' Outbound signal configuration designating 3-Wire Lead with Tachometer / Frequency Speed Sensor output.
    • 'ZP' Zone Protected / Impedance Protected with environmental classification, This is a safety code indicating that the fan motor is equipped with internal impedance protection (or electronic protection). It guarantees that if the fan impeller is completely blocked or locked, the circuit will restrict the current flow to prevent the motor from overheating or catching fire.
    • 'MM' Manufacturing Plant & Customer Specification Identification, The first letter indicates the exact Delta Electronics assembly facility or production line where the fan was built (e.g., China or Taiwan). The second letter (or combination) links the item to custom structural specifications required by the client—in this case, matching the proprietary wire harness, specific 3-pin connector layout, and bracket requirements requested by Foxconn/HP.
    • Photos are representative of the model and specifications you will receive; however, the exact factory batch codes, manufacturing dates, and plant location stamps may differ across individual units.
      • '1313T' The first two digits signify the year of manufacture (2013). The next two digits indicate the specific work week of that year (13th week, which falls in late March). The trailing letter represents the specific assembly line shift, production batch number, or sub-lot sequence used during that specific work week.
