SBT5GMFL

Overview

The SBT5GMFL is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. This component operates at a nominal frequency of 2.7 kHz and produces a sound pressure level of 85 dB at a distance of 10 cm. It features a flat tone output and utilizes a DC voltage supply range of 3 to 16 volts. The device is designed for through-hole mounting with two leads and measures approximately 14.2 mm in diameter and 9.4 mm in height. It is rated for operation within a temperature range of -20°C to +70°C.

Feature Summary

• Piezoelectric transduction mechanism for reliable acoustic signal generation
• Flat tone output characteristic suitable for continuous alerting applications
• Through-hole leaded construction for standard PCB integration

Applications

• Electronic equipment status indicators
• Appliance operational alerts
• Security system notification devices

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required voltage and acoustic specifications. Confirm that the package type matches the target printed circuit board layout. Check for any recent updates to the RoHS compliance status or material declarations prior to final procurement authorization.

Selection Notes

Select this component when a flat tone piezoelectric buzzer is required for low-power applications. Ensure the operating voltage falls within the specified 3V to 16V range. Consider the physical dimensions and lead spacing for mechanical fitment on the assembly board. Verify that the ambient temperature conditions do not exceed the rated operational limits.

Part Context

This part belongs to the SBT series of piezoelectric buzzers from Mallory Sonalert Products Inc. The series offers various frequencies and mounting options. The SBT5GMFL specifically denotes a 5mm class device with a 2.7kHz frequency and green lens color, though the lens may be optional depending on the exact configuration.

Replacement Considerations

Consult official substitution guides for equivalent parts with matching electrical parameters and form factor. Direct replacements must maintain similar sound pressure levels and operating voltage ranges. Verify pinout compatibility before integrating alternative components into existing designs.
