Features: brand new and high quality Ultrasonic frequency: 2.4MHZCeramic sheet size: diameter 16 mm X thickness 1.0 mm, plus the size of the rubber sleeve: 20 mm X 6.0 mmThe length of the sticking out line is: 15.5 for cm Atomization amount: about 150ML/hourIt is suitable for all ultrasonic air humidifiers that use 16mm diameter atomizing discs. Reference for ceramic atomizing sheet parameters:Ceramic atomizing chip capacitor 2: JHB16-2.4MHZ Capacitance 8: 16x1.2mmOscillation frequency: 2.40.05MHZResonance impedance: 2.0 Coupling coefficient:> 40%Capacitance 5: >5000hCapacitance: Voltage 0-1600PF Specifications: Material:ABS Size:Approx.1.6cm/0.63inches Working conditions: 1. Water quality requirements, generally drinking water and purified water, capacitor 6 tap water, etc. If used A small amount of capacitor 9 can be appropriately added to the middle or humidifier to help sleep and improve the skin. 2. Working voltage: 60-80V, the commonly used voltage is 24V. If it is used in a household humidifier, it needs to work at a frequency of 2.4M. The working voltage cannot exceed 80V. 3. Work: 20-50, the working temperature of the atomization film is very important. If the temperature is too high, the atomization film will burn out. Generally, the ceramic atomization film will not have such a problem, because it for always works in water. There is cooling. Note: 1.Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order. 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item. Package includes: 1x Atomizing Transducer
