DC Brushless Blower Specifications: Rated voltage 3V DC Operating Voltage Range 2V DC to 3.5V DC Starting Voltage 2V DC (25C power on/off) Rated Speed 15,500 RPM 30% Air Delivery 2.67 L/min Static Pressure 22.96 Pa Rated Current 36mA Rated Power 0.1 Watts Noise Level 18dB(A) @ 1M 26dB(A) @ 0.3M Direction of Rotation Counter-clockwise viewed from front of fan blade Operating Temperature -10C to +70C Storage Temperature -40C to +70C Bearing System Vapo Bearing System Weight 0.89g *Automatic Restart Protection Polarity Protection *In a situation where the fan is locked by an external force while the electricity is on, an increase in coil temperature will be prevented by temporarily turning off the electrical power to the motor. The fan will automatically restart when the locked rotor condition is released. Characteristics: Motor design Single phase, 6-poles Brushless DC motor Insulation Resistance More than 20M between internal stator and lead wire(+) measured at DC 100V. Dimensions 12mm x 12mm x 3mm Dielectric Strength Applied AC 500V for one minute or AC 600V for 2 seconds between housing and lead wire(+) Noise Level Measured in a semi-anechoic chamber with background noise level below 15dB(A). The fan is running in free air with the microphone at a distance of one meter from the fan intake. Input Power, Current & Speed Measured after continuous 10 minute operation at rated voltage in clean air, and at ambient temperature of 25C. Tolerance +20% / -30% on rated power and current. Air Performance Measured by a double chamber. The values are recorded when the fan speed has stabilized at rated voltage. www.element14.com www.farnell.com www.newark.com Page <1> 14/10/14 V1.2 DC Brushless Blower Performance Curves Material: Frame : Thermoplastic LCP Impeller : Thermoplastic LCP Lead Wire : 32 AWG, +Red, -Black 32 AWG, Yellow, 3rd Wire Dimensions Part Number Table Description Part Number DC Brushless Blower MC34109 Important Notice : This data sheet and its contents (the "Information") belong to the members of the Premier Farnell group of companies (the "Group") or are licensed to it.
