SBT12PLMMPPC

Overview

The SBT12PLMMPPC is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc., designed as an internally driven indicator. It operates on a DC input with a current consumption of 15 to 25mA. The device produces a sound pressure level of 85dB at 9V measured at a distance of 10cm. It functions at a frequency of 2.075kHz and utilizes through-hole PC pins for mounting.

Feature Summary

• Internally driven piezoelectric technology
• Through-hole PC pin termination
• Compact circular form factor

Applications

• Industrial equipment status indication
• Medical device audio alerts
• Consumer electronics signaling

Procurement Notes

Verify the specific acoustic output requirements against the 85dB specification at 9V. Confirm that the 2.075kHz frequency aligns with the target application's auditory needs. Ensure the PCB layout supports the through-hole PC pin dimensions for secure mechanical attachment during assembly.

Selection Notes

Select this component when a compact, internally driven piezo buzzer is required for panel or board mounting. The 44.45mm diameter offers a balance between size and acoustic output. Consider the 15-25mA current draw for power budget calculations in low-power designs.

Part Context

This part belongs to the SBT12 series from Mallory Sonalert, which focuses on industrial-grade audio indicators. The series provides various acoustic patterns and mounting options. The SBT12PLMMPPC specifically targets applications requiring reliable, high-volume production compatibility through its standard through-hole configuration.

Replacement Considerations

Consult official Mallory Sonalert documentation for direct cross-references. Verify electrical parameters such as voltage range and SPL before substituting with other piezo buzzers.
