SMT-2225-T

Alarms, Buzzers, And Sirens Overview

The SMT-2225-T is an externally driven piezo transducer manufactured by PUI Audio, Inc. It operates with a drive voltage of 10 V and draws a supply current of 8 mA. The device features a self-resonant frequency of 2.5 kHz and produces a sound pressure level of 80 dB measured at 10 V and 10 cm distance. Designed for surface mount applications, it utilizes solder pads for board attachment. The component supports single-tone operation modes.

Alarms, Buzzers, And Sirens Feature Summary

• Externally driven piezoelectric transducer design
• Surface mount installation via solder pads
• Single-tone operating mode capability

Alarms, Buzzers, And Sirens Applications

• Electronic alarm systems
• Audible status indicators
• Buzzer circuits in consumer electronics

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix variant required for your application, as packaging options such as tape-and-reel (TR) may differ from bulk tray configurations. Confirm RoHS compliance status directly with the manufacturer or authorized distributor, as some sources indicate non-compliance for certain variants. Ensure the drive circuitry matches the 10 V requirement to achieve specified acoustic performance.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a surface-mount piezo buzzer is required for space-constrained designs. The 2.5 kHz resonant frequency provides distinct audible feedback suitable for general indication tasks. Consider the 80 dB SPL rating relative to ambient noise levels. Verify that the external driver can supply the necessary 8 mA current without exceeding voltage limits.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the SMT series of surface-mount transducers from PUI Audio, Inc. It is categorized under alarms, buzzers, and sirens within electronic component classifications. The product line focuses on compact, board-mount solutions for audible signaling in modern electronic assemblies.

Alarms, Buzzers, And Sirens Replacement Considerations

The SMT-2225-T-R is a related variant offering tape-and-reel packaging for automated assembly. Direct substitution requires verifying mechanical footprint compatibility and electrical parameter alignment, specifically the 10 V drive and 2.5 kHz resonance.
