Does the atomizing disc include a driver board?

These listings describe the atomizing disc configurations. Share your driver frequency, waveform, voltage and mounting arrangement so we can review compatibility and the required supply scope.

How should I compare the 20 mm and 25 mm versions?

Compare the ceramic dimensions, complete mounting envelope, electrical connection and resonance window. The 25-1.7-C is a glass composite assembly; it is not a larger direct replacement for either 20 mm disc.

Is the listed atomization rate guaranteed in my equipment?

The 400 mL/h value listed for the pressure contact and glass composite versions is a catalog reference. The catalog does not define the complete driver, water depth or liquid conditions for that output. Confirm performance in your assembly during sample evaluation. No atomization rate is listed for the wired version.

Can I request samples or a production quotation?

Yes. Send the configuration, application, driver information, liquid, mounting requirements and quantity. Sample availability, MOQ, lead time and any requested test documentation are confirmed for the project.

25 mm Glass Composite Atomizing Disc

The YJ Piezo 25-1.7-C combines a 25 mm PZT ceramic element with a bonded glass layer for OEM ultrasonic atomizing assemblies. Compare the ceramic and composite dimensions, pressure contact interface and electrical specifications before driver matching.

Features & Applications

Specification status: Catalog data has been reviewed, but design-critical values and production tolerances must be confirmed during the RFQ review.

Request Specifications & Pricing for 25-1.7-C

Get detailed datasheets, OEM pricing, and lead time for the 25-1.7-C. MOQ and sample availability are confirmed after configuration and quantity review. Confirm the required specification drawing, electrical checks and any batch documentation when requesting a quotation.

The email opens pre-filled with a short spec checklist — partial details are fine. Typical reply within one business day.

Match the disc to your complete assembly

Confirm driver frequency and waveform, voltage, liquid, water depth, sealing, mounting pressure and duty cycle before sample approval. Final dimensions and lead details are confirmed on the order drawing. Configuration drawings are illustrative and are not to scale.

The Curie temperature is a ceramic material property, not an operating-temperature rating. Where listed, the catalog atomization rate is a reference for validation in the complete assembly. Finished-device performance and any medical or regulatory suitability require separate evaluation.
