SBT5VMHFPPC

Overview

The SBT5VMHFPPC is a piezoelectric buzzer from the Mallory Sonalert SBT series, designed for through-hole mounting. It operates on a DC input voltage range of 3.3 to 5VDC and produces a sound pressure level of 90dB. The device features an internal driver circuit, allowing it to function as both a buzzer and an indicator light. Key specifications include a diameter of 44.45mm (1.750 inches) and a working temperature range of -30°C to 65°C. The unit utilizes PC pins for termination and is certified under RoHS standards.

Feature Summary

• Integrated internal driver circuit enables direct connection to logic-level signals without external components.
• Piezoelectric technology provides reliable acoustic output with low power consumption.
• Dual-function design serves simultaneously as an audible alarm and visual status indicator.
• Through-hole construction ensures secure mechanical attachment to printed circuit boards.

Applications

• Medical equipment status indication
• Industrial control panel signaling
• Consumer appliance alerts
• Transportation system notifications

Procurement Notes

Verify that the specific suffix PP indicates the required pin configuration and lead form for your PCB layout. Confirm that the 90dB acoustic rating meets the ambient noise requirements of the installation environment. Ensure the operating voltage range aligns with the system's power supply rails. Check for any regional compliance certifications required for the target market.

Selection Notes

Select this component when a combined audio-visual signal is required in space-constrained designs. The SBT series offers a standardized footprint suitable for various industrial enclosures. Consider the 90dB output level against background noise conditions. Verify that the through-hole mounting method is compatible with the assembly process used.
