SBT12CLHCTPC

Overview

The SBT12CLHCTPC is an internally driven piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates on a 2.8V peak-to-peak square wave input and delivers a sound level of 85dB at 9V with a frequency of 2.075kHz. The device draws 15 to 25mA and features a rated power of 1W, with a maximum rating of 1.5W. Designed for through-hole mounting via PC pins, it measures 44.45mm in diameter. The unit complies with medical specifications under IEC60601-1-1-8 standards.

Feature Summary

• Internally driven piezoelectric transducer generating oscillating signals
• Compliant with medical safety specifications IEC60601-1-1-8
• Through-hole mounting configuration using printed circuit board pins

Applications

• Medical equipment audible alarms
• Healthcare monitoring devices
• Clinical instrumentation indicators

Procurement Notes

Verify the specific suffix 'HCTPC' against official Mallory documentation to confirm compliance with IEC60601-1-1-8 medical standards. Ensure the required drive signal matches the specified 2.8Vp-p square wave characteristic. Confirm that the through-hole package dimensions align with the target PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when medical regulatory compliance is mandatory for the application environment. The internal driver simplifies circuit design by eliminating external oscillator requirements. Verify that the operating voltage range accommodates the 2.8Vp-p square wave input requirement. Consider the 85dB output level relative to ambient noise conditions in the intended deployment area.
