TP124003-2

Alarms, Buzzers, And Sirens Overview

The TP124003-2 is an externally driven piezoelectric transducer manufactured by DB Unlimited. It features a square surface-mount design with dimensions of 12 mm x 12 mm and a height of approximately 5 mm. The component operates at a rated voltage of 3 V with a current rating of 5 mA. It produces a sound pressure level of 75 dBA at 3 V measured from a distance of 10 cm, with a resonant frequency of 4 kHz. Termination is achieved via gullwing leads for SMD/SMT mounting.

Alarms, Buzzers, And Sirens Feature Summary

• Externally driven piezoelectric technology for reliable acoustic output
• Square surface-mount form factor suitable for compact PCB layouts
• Gullwing lead termination style for automated assembly compatibility

Alarms, Buzzers, And Sirens Applications

• Electronic alarm systems requiring audible indicators
• Buzzer circuits in consumer appliances
• Status indication in portable electronic devices

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific datasheet version for precise mechanical tolerances and soldering profile recommendations. Confirm that the 3V rated voltage aligns with your system's power supply constraints. Ensure PCB pad layout matches the gullwing lead pitch to prevent mounting defects during reflow soldering processes.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a low-profile, square-shaped piezo buzzer is required for surface-mount assembly. It is appropriate for applications needing a 4 kHz tone with moderate volume (75 dBA) powered by a 3 V source. Consider the 5 mA current draw for battery life calculations in portable designs.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the DB Unlimited TE/TP series of electro-mechanical transducers. These components are designed as direct replacements for standard buzzers in various industrial and consumer electronics. The manufacturer specializes in custom and standard audio solutions for space-constrained environments.

Alarms, Buzzers, And Sirens Replacement Considerations

Check pinout compatibility if substituting in existing designs. Verify that the replacement maintains the 3V operating voltage and similar acoustic output levels to ensure functional equivalence without circuit modification.
