FT-15B-42TE

RYD FT-15B-42TE is an ultra-thin piezoelectric ceramic buzzer disc for slim smart home appliances and space-sensitive consumer electronics. With a total thickness of only 0.15mm, the Ø15.0mm element fits housings with strict Z-height limits such as smart switches, control panels and portable gadgets. It operates at 4.2kHz resonance with allowable input up to 30Vp-p and 200MΩ minimum insulation resistance at 9VDC, covering an operating range from -20℃ to +70℃. Customization available: disc dimensions, resonant frequency, electrode layout and lead connection can be adjusted; protective coating on the ceramic surface can be designed to your requirement, and moisture or dust protection options are offered for demanding environments; new developments are welcomed for volume projects. Target scenarios: smart home panels, household appliances, IoT nodes and control equipment.
