This surface-mount device (SMD) includes a piezo disc and resonant cavities in a compact form factor suitable for automated assembly. It requires an external drive signal (e.g., square wave) to function. With a wide frequency range, low power use, and high reliability, it is ideal for compact electronic alarms and indicators, supporting SMT-based automated production.
