SBT12DMHCTPC

Overview

The SBT12DMHCTPC is a medical piezo buzzer manufactured by Mallory Sonalert Products Inc. It features an internally driven piezo transducer with a diameter of 44.45mm and operates via through-hole PC pins. The device produces a drug-fluid sound tone at a frequency of 2.075kHz. Electrical specifications include a current draw of 15 to 25mA and a sound pressure level of 85dB measured at 9V. It is designed for reliable audible signaling in clinical environments.

Feature Summary

• Complies with cUL recognition standards under IEC60601-1-8 AMD1 for medical equipment safety
• Generates a specific drug-fluid acoustic profile suitable for hospital alarm systems
• Utilizes an internally driven piezo mechanism for simplified circuit integration

Applications

• Medical diagnostic machines requiring compliant audio alerts
• Clinical monitoring devices needing standardized warning tones
• Hospital infrastructure alarms adhering to IEC60601-1-8 regulations

Procurement Notes

Verify that the component matches the exact suffix CTPC for through-hole pin configuration. Confirm compliance with IEC60601-1-8 AMD1 requirements for your specific medical application. Ensure voltage ratings align with system design before integration. Request official datasheets from authorized distributors to validate manufacturing origin and quality standards.

Selection Notes

Select this model when strict adherence to medical electrical safety standards is mandatory. The internal drive capability reduces external component count compared to externally driven alternatives. Consider the 85dB output level relative to ambient noise in the intended installation environment. Verify mechanical mounting constraints against the 44.45mm diameter specification.

Part Context

This part belongs to the SBT series of medical piezo buzzers from Mallory Sonalert.
