ST-03BL-1

Alarms, Buzzers, And Sirens Overview

The ST-03BL-1 is an externally driven magnetic transducer manufactured by Soberton Inc. It operates at a rated voltage of 3.6 V with a current consumption of 100 mA. The device produces a sound pressure level of 87 dB measured at a distance of 10 cm. Its resonant frequency is 2.3 kHz. The component utilizes surface mount solder pads for termination and is designed for reflow soldering processes.

Alarms, Buzzers, And Sirens Feature Summary

• Externally driven magnetic transducer design
• Surface mount termination via solder pads
• Reflow compatible construction

Alarms, Buzzers, And Sirens Applications

• Board mount audio indicators
• Alarm systems requiring surface mount buzzers
• Electronic devices needing compact acoustic signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix to ensure correct acoustic output, as variants like ST-03BL differ in decibel levels. Confirm RoHS compliance status through official documentation before procurement. Ensure the ordering part number matches the required 87 dB specification rather than the standard 82 dB version. Check datasheet for reflow profile requirements.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a high-output 87 dB signal is required at 3.6 V. Compare against ST-03BL if lower volume is acceptable. Consider the 2.3 kHz frequency for audibility needs. Verify surface mount compatibility with PCB layout constraints. Ensure the external drive circuit can supply 100 mA continuously.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the ST Series dynamic receivers from Soberton Inc. These are board-mount buzzers designed for electronic equipment. The series includes various models with different acoustic outputs and frequencies. They are generally used for audible alerts in consumer and industrial electronics.

Alarms, Buzzers, And Sirens Replacement Considerations

ST-03BL is a similar variant but provides 82 dB instead of 87 dB. ST-03BH offers higher frequency and volume. Verify pinout and mounting dimensions match the existing PCB footprint before substitution.
