FTBS-40T-3.8A2

RYD FTBS-40T-3.8A2 is a high-capacitance piezoelectric ceramic buzzer disc with RoHS compliant materials, designed for loud and reliable sound indication. The Ø40.0mm brass plate and Ø30.0mm ceramic disc resonate at 3.8±0.5kHz with electrostatic capacitance of 120.0nF at 100Hz, moving substantial air volume at up to 30Vp-p from -20℃ to +70℃ and easing driver design where high output is expected from standard circuits. RoHS compliant materials. 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 waterproof or dustproof options are available; new designs can be developed for volume projects. Target scenarios: industrial alarm devices, automotive signaling, security sirens and consumer electronics.
