  • The Sunon KD1204PFB3 is a compact, high-quality 12V DC brushless axial cooling fan measuring 40mm x 40mm x 10mm. It is widely trusted for tight thermal management requirements across electronic, networking, and legacy compute environments.
  • KD1204PFB3 11.(2).B4086.A.GN ZP KEEN F84A28 Part Number Breakdown:
    • 'KD' Series Code (Sunon KD-Series DC Brushless Fan).
    • '12' Voltage (12V DC).
    • '04' Frame Size (40mm x 40mm).
    • 'P' Frame Material (PBT Plastic).
    • 'F' Frame Thickness (10mm profile).
    • 'B' Bearing System (Double Ball Bearing).
    • '3' Speed Rating (Low Speed relative to the 4010 series baseline, clocking at 5,800 RPM).
    • '11' Legacy Sunon design revision configuration code.
    • '(2)' Number of Motor Poles (Typically designates standard 4-pole phase configuration or internal circuit evolution).
    • 'B4086.A' Internal engineering project tracking code designating specific wire configurations, customized 2.54mm-pitch 2-pin connector termination, or customer-specific wire lead layout (3-inch total length).
    • 'GN' Green/RoHS Compliant (Built using lead-free, environmentally safe components).
    • 'ZP' Impedance Protected (Protection Rating): In electronic motor components, ZP stands for Zone Protected or more commonly Impedance Protected (often paired with "Thermally Protected" or "Z.P." stamps). It indicates that even if the fan blades are physically locked or blocked from spinning while powered, the internal coil impedance restricts the current flow. This prevents the motor from overheating or catching fire..
    • 'KEEN' Customer Sub-Assembly or Plant Designation: KEEN is an internal engineering modifier or sub-assembly route code. It is often tied to a specific sub-contracted equipment manufacturer (OEM), a particular factory line assembly standard, or a bulk-packaged production variant intended for industrial procurement.
    • 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.
      • 'F84A28' Production Lot & Batch Traceability: F84A28 is an exact factory date, lot, or batch traceability matrix code. It tells the manufacturer exactly which factory location, automated line, and date shift built that specific unit. Quality assurance teams use these exact characters to trace back engineering components if a product recall or batch defect arises.
