Procurement Notes

Verify the specific ordering suffix and mechanical dimensions against your PCB layout requirements before finalizing procurement. Confirm that the external driving circuit requirement aligns with your system architecture, as this component does not include an integrated oscillator. Ensure compatibility with your target operating voltage range of up to 30V peak-to-peak to prevent damage or performance degradation during integration.

Selection Notes

Select this transducer when a high-sensitivity, low-current audio indicator is required for through-hole assembly. Its integrated capacitor simplifies drive circuitry compared to bare piezo elements. Consider the 4.25 kHz resonant frequency for optimal audibility in noisy environments. Evaluate the 84 dBA output level against regulatory noise limits and user comfort requirements for the intended enclosure space.
