FT-35B-32E

RYD FT-35B-32E is a large-format piezoelectric ceramic buzzer disc on brass plate for applications that need broad coverage and moderate low-frequency presence. The Ø35.0mm element with Ø25.0mm ceramic disc resonates at 3.2±0.5kHz with maximum resonant impedance of 400Ω and static capacitance of 33nF at 100Hz, accepting up to 30Vp-p input over an operating range of -20℃ to +60℃. Its 0.60mm total thickness adds structural stiffness, fitting consumer electronics indicators, control panels, household appliances and automotive signaling where a larger sounding area is preferred. Customization available: resonant frequency and impedance can be adjusted through dimension tuning, electrode layout and lead wire connection are configurable, protective coating on the ceramic surface can be applied as required, and moisture or dust protection options are offered; new designs can be developed for volume projects. Target scenarios: consumer electronics, smart home appliances, industrial control panels and automotive equipment.
