ST-03BL Description

Short technical summary and product information.

The ST-03BL is a magnetic transducer buzzer from Soberton Inc., designed for applications requiring an audible alert or tone. It operates at a rated voltage of 3.6V with an operating voltage range of 2.5V to 4.5V. The buzzer produces a sound pressure level of 82dB at 10cm when driven at its rated frequency of 2300Hz with a square wave signal.

 

This component is an externally driven transducer, meaning it requires an external drive circuit to generate the audio signal. It features a side port and is housed in a compact 8.5mm x 8.5mm x 3.0mm surface-mount package with solder pad terminations. The housing is made of black LCP material.

 

Key electrical specifications include a maximum current consumption of 100mA and a coil resistance of 16Ω ±3Ω. The buzzer is rated for operation over a temperature range of -20°C to +70°C and can be stored between -30°C and +80°C. It is RoHS compliant and has an MSL rating of 1 (unlimited).
