KD1204PKB1.(2).GN – TBC

The KD1204PKB1.(2).GN is a 12VDC brushless DC fan manufactured by Sunon, conforming to RoHS compliance standards. This fan features a 40mm x 40mm x 20mm form factor, indicated by the “1204” in the part number, where “12” signifies 12V operation, and “04” represents the 40mm dimension. The “PK” designation likely refers to the fan’s bearing type, potentially a precision ball bearing system designed for enhanced longevity and reduced noise compared to sleeve bearings. The “B1” likely denotes a specific wiring configuration or performance characteristic within the KD1204 series, such as a standard 3-pin connector for power, ground, and tachometer output for speed monitoring. The “(2)” likely represents a specific revision or sub-model within the KD1204PKB1 series, potentially indicating minor variations in airflow, static pressure, or power consumption. The “GN” suffix likely indicates a specific lead wire type or termination.
