Overview
The PT-1340P-P7.6PQ is an externally driven piezoelectric buzzer from Mallory Sonalert Products Inc., designed for through-hole mounting on printed circuit boards. It operates within a voltage range of 5 to 25 VPP and produces a sound pressure level of 85 dBA at a frequency of 4.0 kHz. The component features a compact cylindrical form factor with a diameter of 14 mm and a maximum height of 7.7 mm, utilizing solder pin termination for secure board integration.
Feature Summary
- Externally driven piezoelectric transducer requiring external driver circuitry
- Compact low-profile design suitable for space-constrained PCB applications
- Through-hole solder pin termination for reliable mechanical and electrical connection
Applications
- Electronic equipment status indication
- Control panel audio alerts
- Industrial machinery warning signals
Procurement Notes
Verify the specific suffix P7.6 against manufacturer documentation to confirm lead times and packaging details. Ensure driver circuit compatibility with the 5-25 VPP input range. Confirm RoHS compliance status via official datasheets before finalizing procurement specifications.
Selection Notes
Select this component when a high-intensity 85 dBA alert is required in a compact footprint. The 4.0 kHz frequency offers distinct audibility. Ensure the host circuit provides appropriate external drive signals, as this unit lacks internal oscillation. Verify clearance for the 7.7 mm height during PCB layout.
Part Context
This part belongs to the PT series of piezoelectric buzzers manufactured by Mallory Sonalert Products Inc. The series focuses on externally driven transducers optimized for board-level integration. The PT-1340P variant specifically denotes the 14 mm diameter size class within this product line.
Replacement Considerations
Direct substitutes include other PT-series parts with matching 14 mm dimensions and 4.0 kHz frequency, such as PT-1340P variants with different voltage or decibel ratings, provided the external drive requirements remain compatible.
