DC fans are motorized fans powered by direct current electricity, most popularly provided by batteries. They often are little, lightweight, and low-cost, with most designs utilizing brushless DC motors in order to decrease power consumption and expand their lifetime. DC fans, such as the one specified in 109E1348G1D01, are typically applied to regulate the flow of air and dissipate heat which is generated from the internal elements of computers and other electronic components.

The working principle of the 109E1348G1D01 and other DC fans is quite straightforward.The pairs of fan blades are connected to a central hub, while this hub is connected to the motor which is encased within the hub itself. The current supplied to the motor is then utilized to spin the blades, and thus generates a flow of air which runs into the inside of the component, and away from the component. The speed of the fan is regulated via controlling the voltage going to the motor, with the higher voltage values resulting in the faster speed of the blades rotation.

DC fans run on a range of voltage values, with the most popular being either 5 V, 12 V, and 48 V. As said previously, the voltage value can be modulated to regulate the speed of the fan. By adjusting the voltage, the motor then varies its speed accordingly. The minimum voltage is typically around 3.3 V, and the maximum is mostly between 8 V and 13 V, depending on the fan.

DC fans, including the 109E1348G1D01, can also provide features like pulse-width modulation (PWM) or voltage reduction to the user. PWM technology permits the user to adjust the speed of the fan by generating a pattern of high and low voltages to the motor, while voltage reduction permits the user to run the fan at lower speeds in order to reduce noise. Most DC fans come with an output connector that can be connected to the motherboard, or other devices, to let the fan receive the motherboard’s signal to receive the PWM or voltage reduction instructions.

The 109E1348G1D01 DC fan is rated at 6 Watts, 0.25 Amps maximum, and operates at 24-48 V DC range. The 990 RPM fan produces 25.8 CFM airflow, 13 dBA minimum noise level, and also has a MTTF of 50,000 hours. It features an UL 94V-0 FFC (Flexible Flat Cable) cable that allows for quick and efficient connection.

In conclusion, the 109E1348G1D01 DC fan is a reliable and efficient fan designed to regulate the flow of air and dissipate heat while can also improve air quality inside electronic components. The fan features PWM and voltage reduction technologies that allow the user to adjust the speed of the fan accordingly. This fan is also well designed to maximize the motor lifespan, and its UL 94V-0 approved FFC cable makes installation a breeze.
