Dimensions and Mounting
The frame measures 20.0 ± 0.3 mm square, with 16.0 ± 0.15 mm mounting-hole centres and three Ø2.40 ± 0.15 mm mounting holes. Overall thickness is 10.2 ± 0.2 mm. Confirm the mechanical drawing and approved specification before final design release.
Available Functions
Model configurations can include motor-protection functions, FG/RD/RDB/LD signal outputs and PWM speed control. Confirm required options, wire length and connector when requesting a quotation.
How to Select a 20 mm DC Cooling Fan
For a small DC axial fan, evaluate available installation space, supply voltage, required airflow, system resistance, acoustic limit and operating environment. The JF2010 is suitable when a 20 mm fan with increased depth and static-pressure capability is needed.
