SMT-0824-TW-5V-R

Alarms, Buzzers, And Sirens Overview

The PUI Audio SMT-0824-TW-5V-R is an electromagnetic transducer designed for surface-mount applications. It operates on a 5V peak-to-peak input signal with a current draw of 60mA maximum at rated voltage. The device produces a sound pressure level of 85 dBA at a frequency of 2.4 kHz. It functions within a voltage range of 3 to 8V and supports a temperature range of -40°C to 85°C. The component features a square LCP housing measuring 8.5mm x 8.5mm with a maximum height of 5.5mm.

Alarms, Buzzers, And Sirens Feature Summary

• Electromagnetic construction utilizing LCP housing for durability
• External drive capability requiring zero-to-peak input signals
• Surface-mount termination for automated PCB assembly

Alarms, Buzzers, And Sirens Applications

• Space-constrained electronic devices requiring clear audio output
• Industrial control panels needing audible status indicators
• Consumer electronics with limited internal volume

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific ordering suffix to ensure the correct voltage rating and packaging configuration match your design requirements. Confirm that the external driver circuit can supply the required 60mA peak current without exceeding the 8V maximum operating limit. Ensure the PCB layout accommodates the 8.5mm x 8.5mm footprint and allows for proper acoustic porting from the top of the unit.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact, high-output electromagnetic transducer is needed for space-limited designs. It is suitable for applications requiring a distinct audible tone driven by external logic or microcontrollers. Consider the 85 dBA output level against ambient noise requirements and verify compatibility with the system's available drive voltage range between 3V and 8V.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the SMT series of surface-mount transducers from PUI Audio. These components are engineered for board-level integration in modern electronics where traditional through-hole packages are impractical. The series offers various frequencies and sound pressure levels to suit different alerting needs while maintaining a consistent low-profile form factor.

Alarms, Buzzers, And Sirens Replacement Considerations

The SMT-0827-TW-5V-R is a documented alternative within the same product family. It shares similar mounting dimensions but operates at a higher frequency of 2.73kHz and provides 85dB SPL. Verify that the change in resonant frequency does not affect the audibility requirements of the application before substituting.
