SBT12DLHFPPC

Overview

The SBT12DLHFPPC is a piezoelectric buzzer from Mallory Sonalert Products Inc., designed for industrial audio indication. It operates within a voltage range of 9 to 12 VDC and draws 1A of current. The device produces a sound pressure level of 100dB at a distance of 122cm, with a frequency of 1.25kHz. It features an internal driver circuit and supports pulse or slow operating modes. The unit measures 44.45mm in diameter and 15mm in height, utilizing solder pin termination for PCB mounting. It functions reliably between -30°C and +65°C.

Feature Summary

• Integrated internal driver circuit for direct connection
• Industrial-grade construction with screw terminal options available in the series
• Piezoelectric technology for high-efficiency sound generation
• Certified for safety standards including CE, cUL, SAE, and UL

Applications

• Industrial machinery status indicators
• Medical equipment alarm systems
• Automotive control panel alerts
• General purpose audible signaling devices

Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure correct acoustic output and mounting style. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability varies by region. Ensure the selected variant matches the required voltage and current specifications for the target application environment.

Selection Notes

Select this component when a high-decibel, internally driven indicator is required for PCB integration. Consider the 1A current draw for power supply sizing. Evaluate the 100dB SPL requirement against ambient noise levels. Verify that the 9-12VDC input aligns with the system logic or power rails before finalizing the design.

Part Context

This part belongs to the SBT series of industrial buzzers from Mallory Sonalert. The series offers various acoustic patterns and mounting styles. The SBT12DLHFPPC specifically denotes a 12VDC, 100dB, general-purpose or cardiac tone variant with specific physical dimensions. It is distinct from lower-volume or different voltage variants within the same product family.

Replacement Considerations

Direct substitutes include other SBT series parts with matching 12VDC operation and similar SPL ratings. Verify pinout compatibility and mechanical footprint before swapping. Consult the manufacturer's cross-reference guide for exact functional equivalents.
