SBT5ELMFPPC

Overview

The SBT5ELMFPPC is an internally driven piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates within a voltage range of 2.075 kHz frequency and delivers an acoustic output of 85 dB at 3.3V. The device draws between 15 to 30 mA of current and utilizes through-hole PC pin termination for panel mounting. This component is designed for reliable audio indication in industrial applications requiring specific supply failure signaling.

Feature Summary

• Internally driven piezoelectric design for simplified circuit integration
• Specific equipment supply failure melody output capability
• Through-hole PC pin construction for secure panel mounting

Applications

• Industrial equipment supply failure monitoring
• Audio indication systems requiring specific melodic alerts
• Panel-mounted alarm units in controlled environments

Procurement Notes

Verify the exact suffix configuration against official Mallory Sonalert documentation to ensure correct melody and electrical specifications. Confirm that the through-hole PC pin format matches your PCB layout requirements. Cross-reference the part number with the latest sales outline drawing to validate mechanical dimensions and mounting hole specifications before procurement.

Selection Notes

Select this component when a specific supply failure melody is required rather than a standard tone. Ensure the operating voltage aligns with the 3.3V reference for the specified 85 dB output level. Verify that the 15-30 mA current draw is compatible with the driving circuit capabilities and that the through-hole form factor fits the assembly constraints.

Part Context

This part belongs to the Mallory Sonalert SBT5 series, which provides industrial-grade audio indicators. The ELMFPPC suffix denotes specific electrical and mechanical characteristics, including the piezoelectric element type and mounting style. It is distinct from other variants in the series that may offer different frequencies, sound levels, or drive methods.

Replacement Considerations

Consult official Mallory Sonalert substitution guides for verified equivalents. Generic piezo buzzers may not replicate the specific supply failure melody or acoustic profile. Verify that any substitute matches the 2.075 kHz frequency and 85 dB output specification to maintain system compliance.
