SBT12CHCSPPC

Overview

The SBT12CHCSPPC is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It features internal drive circuitry and accepts DC input within a voltage range of 9 to 12VDC. The device operates at a frequency of 1kHz with a sound pressure level of 90dB. Designed for cardiac applications, it utilizes through-hole termination and measures 44.45mm in diameter.

Feature Summary

• Piezoelectric technology with integrated internal driver
• Optimized acoustic profile for cardiac alarm signaling
• Through-hole mounting configuration for PCB integration

Applications

• Cardiac monitor alarm systems
• Medical equipment audio indicators
• Hospital patient monitoring stations

Procurement Notes

Verify the specific suffix 'SPPC' against official Mallory documentation to confirm compliance with IEC60601-1-8 standards. Ensure the required operating voltage matches the 9-12VDC specification. Confirm that through-hole PCB layout accommodates the 44.45mm diameter footprint before finalizing procurement orders.

Selection Notes

Select this component when a dedicated cardiac alarm tone is required within medical devices. The internal driver simplifies circuit design by eliminating external oscillators. Verify that the 90dB output meets regulatory noise limits for the intended clinical environment while ensuring compatibility with standard 12VDC power rails.

Part Context

This part belongs to the SBT series of industrial-grade audio indicators from Mallory Sonalert. These components are engineered for reliability in critical signaling roles. The SBT12CHCSPPC variant specifically targets healthcare applications requiring certified acoustic alerts for vital sign monitoring systems.

Replacement Considerations

Cross-reference with SBT12CHCFPPC for potential functional equivalence in similar medical enclosures. Verify pinout compatibility and acoustic performance differences before substituting.
