Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required impedance and sensitivity tolerances. Confirm RoHS compliance status through official documentation prior to integration. Check for any recent manufacturing updates or lifecycle notifications directly from PUI Audio to guarantee long-term supply availability and technical consistency for production runs.

Selection Notes

Select this component when a high-sensitivity, low-power speaker is required for narrow-band audio signaling rather than full-range reproduction. The 32 Ohm impedance matches specific driver circuits efficiently. Consider the 2.1 kHz resonant frequency as the primary operating point for optimal efficiency. Ensure mechanical clearance allows for the 7.50 mm height profile within the target enclosure design constraints.
