SBT5TLMMPPC

Overview

The SBT5TLMMPPC is a through-hole piezoelectric transducer with integrated circuitry, manufactured by Mallory Sonalert Products Inc. It operates at a nominal voltage of 3.3V DC and produces a sound pressure level of 85dB. The device features a variable duration output and operates at a frequency of 2.075kHz. It draws a current of 15 to 30mA. The physical dimensions are approximately 44.45mm in diameter (1.750 inches), designed for board-level mounting via PC pins.

Feature Summary

• Integrated internal drive circuitry for direct connection
• Piezoelectric transduction technology
• Through-hole mounting configuration

Applications

• Board-level audible alarms
• Electronic sound indicators
• Internal drive buzzer applications

Procurement Notes

Verify the specific suffix MMPPC against official Mallory Sonalert documentation to confirm terminal type and packaging details. Ensure compatibility with 3.3V logic levels and verify that the 85dB acoustic output meets regulatory requirements for the intended enclosure. Confirm RoHS compliance status with the manufacturer prior to final design approval.

Selection Notes

Select this component when an internally driven, high-volume piezoelectric buzzer is required for through-hole assembly. The 85dB output at 3.3V makes it suitable for general purpose alerting where moderate loudness is sufficient. Consider the 44.45mm diameter for panel cutout or chassis space constraints.

Part Context

This part belongs to the Sonalert® line of audible signal devices produced by Mallory Sonalert Products Inc. The series typically includes various piezoelectric buzzers and sirens designed for electronic equipment. The SBT5 series specifically denotes board-mounted units with integrated electronics, distinguishing them from passive transducers.

Replacement Considerations

Cross-reference with other Mallory Sonalert SBT5 series variants if different acoustic characteristics or mounting styles are needed. Verify pinout and electrical specifications before substituting with generic piezo buzzers, as internal driver circuits vary significantly between manufacturers.
