Description
The 1804 square cooling fan provides a reliable active air cooling solution within an extremely compact size of 18mm square and 4mm thick. It supports 5V or 3.3V low-voltage DC power supply, boasts extremely low power consumption, and can be directly driven by a battery. Utilizing a silent hydraulic bearing, its operating noise is below 20dBA, making it an ideal choice for controlling temperature rise and ensuring performance in next-generation electronic devices such as TWS earphones, smart wearables, and micro IoT terminals.
18x18x4MM (0.7″x0.7″x0.15″)-DC COOLING FAN SERIES
| MODEL: | FH1804 |
| VOLTAGE: | 3.3V/5V |
| MATERIAL: | Frame: Plastic (UL94V-0)/Impeller: Plastic (UL94V-0) |
| EXPECTED LIFE: | Hydraulic Bearing 30,000hrs (40°C) |
| SAFETY STANDARDS: | CCC, RoHS, CE, ISO9001 |
Ultra-low power consumption, worry-free battery life
– 5V operating current is only 0.05A, power consumption is 0.25W, which has virtually no impact on the battery life of battery-powered devices.
Quiet operation, imperceptible performance
– Full-speed noise is below 24dBA, and at low speed it is only 18dBA, even lower than the background noise in a quiet environment.
Designed specifically for miniature heat sources
– The generated concentrated airflow can directly blow on tiny heat sources such as SoCs and sensors, effectively reducing local junction temperature.
Brushless motor drive:
Reduces electrical sparks, improves reliability, supports PWM speed control, and is suitable for heat dissipation or airflow control in precision electronic equipment.
