25mm 1.7MHz Ultrasonic Atomizer Transducer – 12V Ceramic Disc with 80mm Wire for Humidifier / DIY Mist Maker

The 25mm 1.7MHz Ultrasonic Atomizer Transducer is a high-output replacement component designed for humidifiers, foggers, and DIY mist makers. It features a 25mm ceramic ultrasonic disc that operates at 1.7MHz, delivering higher mist volume than smaller 16mm or 20mm atomizers. The transducer comes pre-wired with 80mm leads, making it a complete drop-in replacement or upgrade solution for compatible humidifier and fogger units.

At the heart of the transducer is a ceramic piezoelectric element that vibrates at 1.7MHz when driven by an appropriate driver circuit. This high-frequency vibration breaks water into fine mist particles, producing a consistent, visible mist output. The 25mm diameter is larger than standard 20mm atomizers, providing a larger atomization surface area for higher mist output — making it ideal for applications requiring more substantial humidification.

The 12V operating voltage is a key feature of this transducer. Unlike standard 5V atomizers, this disc is designed for 12V driver circuits, which are commonly used in automotive, industrial, and larger humidifier applications. The higher voltage allows for efficient atomization with good mist output.

The 1.7MHz operating frequency produces a fine mist with good volume, making it suitable for:

• Home humidifiers — Bedroom, office, and living space humidification

• Commercial humidifiers — Larger spaces and continuous operation

• Aromatherapy diffusers — Scent distribution

• DIY mist makers — Custom fog and mist effects

• Greenhouse misting — Humidity control for plants

• Model-making foggers — Diorama and display effects

The pre-wired 80mm leads simplify installation and replacement. The longer lead length provides additional flexibility for mounting the transducer in different enclosure configurations. The leads are already attached to the disc, eliminating the need for soldering in tight spaces.

The transducer is widely used as a replacement part for ultrasonic humidifiers, fog machines, aromatherapy diffusers, model-making foggers, and DIY misting projects. It is a consumable component that may need periodic replacement depending on water quality and usage conditions.

The transducer is designed for continuous operation when properly immersed in water, with a typical lifespan of 3000–5000 hours.

Important Note: The atomizer transducer must be fully immersed in water during operation. Do not operate the disc dry, as this will cause overheating and permanent damage. Use clean water (preferably distilled) to prevent mineral buildup on the disc surface. Ensure the driver circuit is compatible with the disc’s 1.7MHz frequency and 12V operating voltage.

Whether you are replacing a worn-out atomizer in a humidifier, building a custom mist maker, or upgrading to a higher-output transducer, the 25mm 1.7MHz Ultrasonic Atomizer Transducer provides a reliable, ready-to-install solution. It is suitable for individual makers, repair technicians, and businesses purchasing in bulk for product development or service applications.
