ST-01BH

Alarms, Buzzers, And Sirens Overview

The ST-01BH is an externally driven magnetic buzzer manufactured by Soberton Inc. It operates at a resonant frequency of 2.73 kHz and requires a drive voltage between 2V and 4V. The component draws a current of 70 mA during operation. Designed for surface mount technology (SMD), it features solder pad terminations for PCB integration. The physical dimensions are 11 mm by 14 mm, making it suitable for compact electronic assemblies requiring audible signaling.

Alarms, Buzzers, And Sirens Feature Summary

• Externally driven magnetic transducer design
• Surface mount construction with solder pad termination
• Fixed resonant frequency output

Alarms, Buzzers, And Sirens Applications

• Electronic device alarm systems
• Audible status indicators in consumer electronics
• Control panel signaling units

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and mechanical mounting details before finalizing designs. Ensure the driving circuit can supply the required 70 mA current at the specified voltage range. Confirm RoHS compliance status if environmental regulations apply to the end product assembly process.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a fixed-frequency audible alert is required in a space-constrained application. The external drive requirement necessitates a compatible driver circuit within the system design. Consider the SMD form factor for automated assembly processes and verify that the operating voltage aligns with the available power rails.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Soberton Inc. line of alarms, buzzers, and sirens. It is categorized as a magnetic transducer designed for surface mount applications. The series includes various models with different frequencies and drive requirements, serving general purpose audible notification needs in commercial and industrial electronics.

Alarms, Buzzers, And Sirens Replacement Considerations

Check for direct substitutes such as the ST-04BT or other ST-series variants from Soberton Inc. Verify that any replacement matches the 2.73 kHz frequency, 70 mA current draw, and 11x14 mm footprint to ensure mechanical and electrical compatibility without redesigning the host circuit board.
