SBT12EMPC

Overview

The SBT12EMPC is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc., designed for medical equipment applications. It operates on a DC input voltage range of 9 to 12VDC and produces a sound pressure level of 90dB at 10cm. The device features an internal driver circuit and utilizes through-hole solder pin termination for PCB mounting. It is certified under cUL standards, specifically recognized to IEC60601-1-8 AMD1 for supply failure melody indications in medical devices.

Feature Summary

• Certified for medical use with cUL recognition to IEC60601-1-8 AMD1 standard
• Internal driver circuit enables direct connection to control logic
• Piezoelectric technology ensures reliable acoustic output
• Designed specifically for supply failure melody indication

Applications

• Medical equipment supply failure indication
• IEC60601-1-8 compliant audio alerts
• Hospital infrastructure alarm systems

Procurement Notes

Verify that the specific variant matches the IEC60601-1-8 AMD1 certification requirements for your intended medical application. Confirm the operating voltage aligns with the 9-12VDC specification. Ensure the through-hole mounting style is compatible with your PCB layout. Check for current regulatory compliance documentation before finalizing procurement.

Selection Notes

Select this component when a medically certified piezoelectric buzzer is required for critical alarm functions. The internal driver simplifies circuit design by removing the need for external oscillators. Consider the 90dB acoustic output for environments requiring clear audible warnings. Verify mechanical fitment for through-hole installation on the target board.
