SKU CH-V87V-RRTX0

Ultra-compact 5 V blower fan measuring 18 mm square draws only 0.05 A for silent cooling in tight spaces

  • TypeCase Fan
  • Ultra-compact 18×18×4 mm footprint fits tight enclosures
  • Low 5 V, 0.05 A draw suits USB or battery power
  • Silent blower operation keeps noise minimal in quiet builds
  • Focused airflow targets PM2.5 sensors or drone hot-spots
  • Solid-state switch control enables simple on/off or PWM speed regulation

Compact 5 V blower for tight spaces

The CAFELE RFB1804 is an 18 mm square blower just 4 mm thick that runs on 5 V at 0.05 A. Its miniature frame delivers focused airflow where full-size case fans cannot fit.

Suits embedded builds and sensor cooling

This fan serves developers adding active cooling to PM2.5 detectors, small drones or other space-constrained electronics. Builders who need high static pressure for radiators or large-volume case airflow should look at larger models.

5 V 0.05 A power rating

The blower draws only 0.05 A at 5 V so it can be powered directly from a microcontroller header or a USB port. Verify that your board can supply this current before connecting.

Soalan tentang produk ini

Does the 5 V 0.05 A rating mean I can power the RFB1804 directly from a standard motherboard fan header?

Yes — the blower draws only 0.05 A at 5 V, well within the current limit of a typical 5 V fan header, so no external adapter is required.

Will the 18 mm square frame line up with the mounting points on my existing 18 mm fan cut-out?

The RFB1804 measures 18×18 mm, so it matches the same footprint and screw spacing as other 18 mm fans you may already have installed.

How can I confirm the blower is spinning at the correct speed after installation?

Connect the fan, power the system, and verify airflow from the outlet; the unit is rated for silent operation, so you should hear only a faint whir with no rattling or vibration.
