Product Details

40x40x20mm DC axial fan - 40mm pressure reserve

40x40x20mm 40mm 4020 DC Cooling Fan Series 5V 12V 24V Dual Ball Bearing is selected when the airflow path has more resistance than an open board. It fits small power supplies, dense electronics boxes and grille-backed vents. Select 4028 for stronger static pressure in narrow channels.

Mounting point: 40x40x20mm / 4020; the airflow path has more resistance than an open board.
Voltage range: 5V / 12V / 24V; 2-wire, 3-wire, FG, RD or PWM options can be reviewed by project.
Flow behavior: balanced airflow to confirm by datasheet or sample; best for small power supplies, dense electronics boxes and grille-backed vents.
Custom item: SXD4020-5V, SXD4020-12V, SXD4020-24V; confirm cable length, connector, label and packing before production.
