SBT12CLMCTPC

Overview

The SBT12CLMCTPC is an internally driven piezoelectric buzzer from the Mallory Sonalert SBT series. It operates on DC input with a supply voltage range of 9V to 12V. The device produces a sound pressure level of 85dB at 9V measured at 10cm distance. Its operating frequency is 2.075kHz, and it draws between 15mA and 25mA. The unit features through-hole PC pins for mounting and has a diameter of 44.45mm (1.750 inches).

Feature Summary

• Internally driven active buzzer with built-in driving circuitry.
• Piezoelectric technology for reliable acoustic output.
• Through-hole PC pin termination for standard PCB mounting.

Applications

• Medical equipment alarms requiring cUL recognition to IEC60601-1-8 AMD1.
• Cardiac melody signaling applications.
• General industrial alarm systems.

Procurement Notes

Verify the specific ordering suffix matches the required acoustic specifications and mounting style. Confirm RoHS3 compliance status if environmental regulations apply to your assembly process. Ensure the DC supply voltage aligns with the 9V to 12V operational range to maintain the specified 85dB SPL performance. Check that the through-hole footprint corresponds to your PCB design requirements.

Selection Notes

Select this component when an active, internally driven piezo buzzer is required for medical or industrial signaling. The cUL recognition to IEC60601-1-8 AMD1 makes it suitable for healthcare environments. Consider the 2.075kHz frequency and 85dB output for audibility needs. The through-hole package dictates the manufacturing assembly method.
