Procurement Notes
Verify the specific suffix and voltage rating against the target application requirements. Confirm that the through-hole footprint matches the design layout. Ensure the operating environment temperature range aligns with the component specifications. Cross-reference the manufacturer part number to avoid confusion with similar series items.
Selection Notes
Select this component when a high-decibel audible indicator is required for 12V DC systems. Consider the 3.5 kHz resonant frequency for optimal efficiency in alert applications. Evaluate the physical dimensions to ensure adequate clearance on the printed circuit board. Compare against electromagnetic alternatives if lower power consumption is critical.
Part Context
This part belongs to PUI Audio's line of piezoelectric transducers intended for continuous tone generation. It serves as an alternative to active buzzers where discrete driving circuits are preferred. The product family emphasizes durability and consistent acoustic performance across various industrial and commercial environments.
Replacement Considerations
Direct substitutes may include other 12V piezoelectric transducers from PUI Audio with similar acoustic output. Verify compatibility with existing drive circuits before substitution. Check mechanical dimensions to ensure fit within the designated enclosure space.
