WT-0905T-3V

Alarms, Buzzers, And Sirens Overview

The WT-0905T-3V is an externally driven magnetic buzzer transducer manufactured by Soberton Inc. It operates at a rated voltage of 3 V with a current draw of 50 mA to 70 mA. The device generates a sound pressure level of 80 dB at a distance of 10 cm, operating at a frequency of approximately 2.713 kHz to 2.73 kHz. It features through-hole PC pin termination and has a physical height of 9.2 mm. The component does not include a built-in drive circuit.

Alarms, Buzzers, And Sirens Feature Summary

• Externally driven magnetic transducer design
• Through-hole mounting with PC pins
• High sound pressure output capability

Alarms, Buzzers, And Sirens Applications

• Electronic alarm systems
• Audible status indicators in consumer electronics
• Control panel feedback mechanisms

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific current rating (50 mA vs 70 mA) required for your application against the official datasheet, as sources vary slightly. Confirm that the external drive circuit matches the 3 V operation requirement. Ensure PCB layout accommodates the through-hole PC pin spacing and 9.2 mm height constraint. Check if washability is required, as this model is typically non-washable.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a low-voltage, high-volume audible indicator is needed without internal oscillation circuits. It requires an external square wave signal source. Compare against the WST-0905T series if a 5 V supply or different acoustic profile is necessary. Ensure the driving logic can handle the specified current load at 3 V.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the WT Series of magnetic buzzers from Soberton Inc., designed for simple, reliable audible signaling. Unlike piezoelectric types, these require an external driver but offer robust performance at low voltages. The series includes variants with different voltage ratings and acoustic outputs.

Alarms, Buzzers, And Sirens Replacement Considerations

The WST-0905T is a related variant but operates at 5 V, requiring circuit adjustment. Direct substitutes must match the 3 V rating, magnetic type, and through-hole pin configuration. Verify acoustic output and frequency compatibility before substitution.
