Alarms, Buzzers, And Sirens datasheet and documents for SMT-1720-T-HT

SMT-1720-T-HT

Alarms, Buzzers, And Sirens Overview

The SMT-1720-T-HT is a surface-mount electromagnetic transducer manufactured by PUI Audio. It features a 17mm diameter and operates with a maximum supply voltage of 16V. The device has a resonant frequency of 2kHz and a current rating of 50mA. It delivers a sound pressure level of 95dB at 10cm distance when driven at 12V. The impedance is 120 ohms, and it utilizes solder pads for board mounting.

Alarms, Buzzers, And Sirens Feature Summary

High sound pressure level output of at least 95 dB measured at 10 cm distance
Surface mount construction designed for automated assembly processes
Externally driven magnetic transducer mechanism

Alarms, Buzzers, And Sirens Applications

Electronic alarm systems requiring audible alerts
Buzzer circuits in consumer appliances
Industrial control panel indicators

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and mechanical dimensions before finalizing design integration. Ensure that the driving circuit can provide the required 50mA current rating without exceeding the 16V maximum supply voltage limit. Confirm compatibility with the target PCB footprint and soldering profile requirements for surface mount technology.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a high-output audible indicator is needed in a compact surface-mount form factor. The 120-ohm impedance and 2kHz resonant frequency define the acoustic performance characteristics. Consider the 17mm diameter constraint against available board space. This part is suitable for applications requiring externally driven operation rather than integrated oscillator buzzers.

Alarms, Buzzers, And Sirens Part Context

This transducer belongs to PUI Audio's surface-mount electromagnetic series. It is distinct from piezoelectric alternatives due to its magnetic drive mechanism. The model designation indicates specific acoustic and electrical parameters tailored for general-purpose audible signaling in electronic devices where space efficiency is prioritized over low power consumption.
