PROJECTS UNLIMITED Surface Mount Audio Buzzer, 88dBA, 2.4kHz

The PROJECTS UNLIMITED SMI-1324-TW-5V-2-R is a compact, high-performance surface mount audio indicator designed for modern electronic assemblies. This buzzer delivers a clear, continuous tone at a resonant frequency of 2.4kHz with a substantial sound pressure level of 88dBA, ensuring your auditory alerts are both noticeable and reliable.

Engineered for durability and easy integration, it features a robust PPS (polyphenylene sulfide) housing that offers excellent chemical and thermal resistance. The terminals are constructed from brass with a protective tin plating, ensuring strong solderability and long-term connection integrity. Its low-profile case configuration, at just 6.5mm in height, makes it ideal for space-constrained PCB designs.

A key feature for post-assembly processing is the sealed case with a removable tab, which allows the component to be safely cleaned using various washing processes without risk of damage or contamination. It is fully compatible with convection, infrared (IR), and vapour phase reflow soldering techniques, providing flexibility in your manufacturing workflow.

Built to operate in demanding environments, this audio transducer functions reliably across a wide operating temperature range from -40°C to +85°C. With a supply voltage range of 4V to 7V and a current rating of 30mA, it offers efficient performance for a variety of low-voltage applications where a clear audible signal is required.
