Loud 95dB Piezo Buzzer DC324V

SFM20B piezo buzzer: 26 mm × 27 mm × 10 mm form factor, 8 g weight. Rated voltage: DC 324V (tested and stable between 5–32V DC). Acoustic output: 95 dB (measured per IEC 60651 at 10 cm, free-field conditions). Tone type: continuous, single-frequency (resonant frequency ~2.7 kHz). Terminals: axial leads, tinned copper, 0.5 mm diameter, 2.54 mm spacing. Built for durability in real-world electronics integration — resistant to humidity, dust ingress (IP52-rated enclosure), and electrical transients common in automotive ignition systems. No polarity sensitivity; operates regardless of DC lead orientation. Low quiescent current draw (
