SBT5DLMCTPC

Overview

The SBT5DLMCTPC is an internally driven piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates on a DC voltage range of 3.3V to 5VDC and produces a sound pressure level of 85dB at a distance of 10cm. The device functions at a frequency of 2.075kHz with a current draw between 15mA and 40mA. It utilizes through-hole PC pin termination for board mounting. The component is designed for industrial applications and complies with RoHS standards.

Feature Summary

• Internally driven piezoelectric design for simplified circuit integration
• Through-hole PC pin termination for secure board mounting
• Compliance with RoHS environmental directives

Applications

• Industrial panel alarms
• Medical equipment audio indicators
• Consumer electronics alerts

Procurement Notes

Verify the specific suffix 'CTPC' against official Mallory Sonalert documentation to confirm terminal type and acoustic characteristics. Ensure the operating voltage matches the 3.3V-5VDC requirement. Confirm that the 85dB output meets the intended application's audibility needs. Check for any regional supply restrictions or discontinuation notices from authorized distributors before finalizing procurement plans.

Selection Notes

Select this component when an internally driven solution is required to reduce external driver complexity. The 2.075kHz frequency provides a distinct audible tone suitable for general alerting. The through-hole format is appropriate for prototyping or high-reliability PCB assemblies where surface mount options are unsuitable. Verify thermal limits against the -30°C to 65°C operating range.

Part Context

This part belongs to the SBT5 series of audio indicators from Mallory Sonalert, a manufacturer specializing in sound and visual warning devices. The series includes various acoustic outputs and mounting styles tailored for industrial, medical, and consumer markets. Mallory Sonalert has a long history of producing reliable alarm components since the mid-20th century.

Replacement Considerations

Consult official Mallory Sonalert substitution guides for direct replacements. Generic piezo buzzers may not match the internal drive circuitry or specific acoustic profile. Verify mechanical dimensions and pinout compatibility if considering alternative manufacturers.
