Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct acoustic and electrical specifications. Confirm that the through-hole package style matches the target PCB layout requirements. Check for any recent regulatory compliance updates or RoHS status changes before finalizing procurement orders.
Selection Notes
Select this component when a high-decibel audible alert is required within a limited spatial footprint. The internal driver simplifies circuit design by eliminating external oscillators. Ensure the supply voltage falls within the 15-40V DC range to achieve the specified 85dB performance level without overdriving the element.
