FAQ

Q: Is this buzzer active or passive? A: It is passive piezo buzzer. Square wave signal is needed, cannot be driven directly by DC power.

Q: What benefits does LCP housing bring? A: LCP material features good thermal stability, suitable for environments with large temperature fluctuation.

Q: Why choose this 9mm ultra-thin buzzer? A: It saves PCB space, perfect for slim and mini electronic products with limited internal space.
