SBT12PHCSPPC

Overview

The SBT12PHCSPPC is an internally driven piezo buzzer manufactured by Mallory Sonalert Products Inc. It operates within a voltage range of 9 to 12 VDC and draws a current between 15 and 25 mA. The device produces a sound pressure level of 85 dB at 9 V, with a frequency of 2.07 kHz. It features a diameter of 44.45 mm and utilizes through-hole PC pins for PCB mounting.

Feature Summary

• Internally driven piezo technology
• Through-hole PC pin termination
• Round housing design

Applications

• Medical alarm indicators
• Industrial control panels
• Consumer electronics alerts

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct electrical characteristics and mounting style. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to procurement. Ensure compatibility with existing PCB layouts regarding hole spacing and pin configuration.

Selection Notes

Select this component when an internally driven solution is required for space-constrained designs. The 44.45 mm diameter suits standard panel cutouts. Compare acoustic output requirements against the 85 dB specification at 9 V. Consider thermal limits if operating near maximum voltage ratings in enclosed environments.

Part Context

This part belongs to the Mallory Sonalert audible warning device portfolio. The brand specializes in industrial, medical, and military audio indicators. The product line includes various piezo and electromagnetic buzzers designed for reliable alerting in harsh environments.

Replacement Considerations

Mallory Sonalert provides cross-reference sheets for obsolete Murata buzzers. Verify equivalent part numbers using official Mallory documentation before substitution. Ensure mechanical dimensions and electrical parameters match the original design requirements.
