SBT12GHCMPPC

Alarms, Buzzers, And Sirens Overview

The SBT12GHCMPPC is an internally driven piezo buzzer from the Sonalert series, manufactured by Mallory Sonalert Products Inc. It features a resonant frequency of 2.075 kHz and produces a sound pressure level of 85 dB at 9 V. The device operates with a current consumption between 15 mA and 25 mA. Designed for through-hole mounting via PC pins, it has a diameter of 44.45 mm and a height of approximately 10 cm including leads. The unit is rated for operation within standard industrial temperature ranges and complies with relevant safety standards.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezoelectric design eliminates need for external oscillator circuits
• Through-hole PC pin termination facilitates direct PCB integration
• High-priority audible warning capability compliant with medical alarm standards

Alarms, Buzzers, And Sirens Applications

• Medical equipment high-priority alarms
• Industrial control panel indicators
• Safety warning systems in electronic devices

Alarms, Buzzers, And Sirens Procurement Notes

Verify RoHS compliance status and specific datasheet revisions before procurement. Confirm lead times as availability may be restricted. Ensure mounting hole dimensions match PCB layout requirements. Check operating voltage compatibility with system power supply rails to prevent damage or insufficient output.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when an internally driven, high-intensity audible alert is required without complex driver circuitry. The through-hole package suits prototyping or high-reliability applications where surface mount options are unsuitable. Consider the 85 dB output level against ambient noise requirements and the 2.075 kHz frequency for optimal human audibility.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Sonalert SBW/SBT series of piezoelectric buzzers. These devices are widely used in industrial and medical sectors for their reliability and loudness. The SBT variant typically denotes through-hole construction with specific acoustic characteristics tailored for general or high-priority signaling applications.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes include other Mallory Sonalert models with similar form factors and electrical ratings, such as SBT12GLCMPPC or SBT12GHCSPPC, provided pinout and acoustic output meet application needs. Verify mechanical dimensions and mounting style compatibility before substitution.
