SBT5LM1PC

Overview

The SBT5LM1PC is a through-hole piezoelectric audio indicator manufactured by Mallory Sonalert Products Inc. It operates on a DC input voltage range of 3.3V to 5VDC. The device produces a general alarm sound with a sound pressure level of 90dB. Designed for panel or board mounting, it features internal drive circuitry and accepts direct DC input. The component is part of the IEC alarm series and complies with RoHS standards.

Feature Summary

• Piezoelectric technology with integrated internal drive circuitry
• High-output 90dB general alarm acoustic profile
• Low-voltage operation compatible with 3.3V to 5VDC systems
• Through-hole mounting configuration for PCB integration

Applications

• General purpose audible alarms in electronic equipment
• Medical device status indicators
• Industrial control panel alerts
• Consumer electronics warning signals

Procurement Notes

Verify the specific acoustic waveform designation against project requirements, as this model is designated for general alarm applications. Confirm that the through-hole package dimensions align with the target printed circuit board layout. Ensure the operating voltage range matches the system power supply specifications to guarantee reliable activation without damage.

Selection Notes

Select this component when a high-volume, low-current audible alert is required for standard DC logic levels. The 90dB output ensures audibility in moderately noisy environments. Consider the physical size and lead spacing constraints during mechanical design. This unit is suitable for designs prioritizing cost-effective, robust signaling over complex melodic tones.

Part Context

This component belongs to the SBT5 series of medical and industrial piezo buzzers from Mallory Sonalert. The series is characterized by compliance with IEC60601-1-8 standards for medical alarms, offering various acoustic patterns including failure, cardiac, and general alarm types within a compact form factor.

Replacement Considerations

Direct substitutes within the same series include SBT5PLMFPPC (Perfusion), SBT5DLHMPPC (Drug-Fluid), and SBT5EMFL (Failure). These units share identical electrical and mechanical interfaces but differ in their programmed acoustic waveforms.
