Description
16MM 108KHZ Universal Humidifier Atomizer Ceramic Ultrasonic Head
The 16 mm 108 kHz Universal Humidifier Atomizer Ceramic Ultrasonic Head is the piezoelectric transducer used in small USB humidifiers and mist makers. It converts high-frequency electrical signals into ultrasonic vibration to produce fine water mist.
Below are the typical specifications used by most 16 mm / 108 kHz atomizer heads.
1. Basic Information
| Parameter |
Value |
| Product type |
Ultrasonic atomizing transducer |
| Atomizer diameter |
16 mm |
| Silicone ring outer diameter |
~20 mm |
| Material |
Piezoelectric ceramic + stainless steel mesh |
| Atomization method |
Ultrasonic vibration |
| Application |
USB humidifiers / aroma diffusers |
The atomizer uses a piezo ceramic plate bonded to a stainless-steel microporous mesh to generate mist.
2. Electrical Specifications
| Parameter |
Typical Value |
| Resonant frequency |
108 kHz ±5 kHz |
| Operating voltage |
3 – 12 V DC (typically 5 V via driver board) |
| Operating current |
~300 mA |
| Power consumption |
1.5 – 2 W |
| Static capacitance |
~3000 pF ±20% |
| Resonant impedance |
≤150 Ω |
These atomizer heads require a driver circuit (like XKT-202 based boards) to generate the correct ultrasonic signal.
3. Atomization Performance
| Parameter |
Value |
| Mist output |
40–50 ml/hour |
| Micro-hole diameter |
~5 µm |
| Number of holes |
~700–800 |
| Particle size |
~3–5 µm mist droplets |
The stainless-steel mesh contains hundreds of microscopic holes that push water through when vibrated ultrasonically.
4. Mechanical Characteristics
| Parameter |
Typical Value |
| Disc diameter |
16 mm |
| Thickness |
~1–1.5 mm |
| Cable length |
~70–100 mm |
| Wire type |
2-wire |
| Mounting |
Silicone rubber ring holder |
5. Operating Conditions
| Parameter |
Value |
| Operating temperature |
5 °C – 45 °C |
| Maximum temperature |
≤85 °C |
| Service life |
≥3000 hours |
A protective anti-oxidation silver coating is often used to extend the life of the atomizer plate.
6. Typical Structure
The atomizer head consists of:
-
Piezoelectric ceramic disc
-
Stainless steel micro-perforated mesh
-
Silicone sealing ring
