Overview
The SBT5TMCFPPC is a piezoelectric audio indicator manufactured by Mallory Sonalert Products Inc. It operates within an IEC voltage range of 3.3V to 5VDC and produces a sound pressure level of 90dB. The device features a temperature-energy sound tone and utilizes internally driven circuitry with a current draw of 15 to 40mA at a frequency of 2.075kHz. It employs a 45mm piezo technology type and is designed for through-hole mounting via five PC pins. This component is part of the IEC60601-1-8 Medical Alarms series, ensuring compliance with medical equipment standards.
Feature Summary
- Complies with IEC60601-1-8 standards for medical alarm applications
- Features internally driven piezoelectric technology for reliable operation
- Designed for through-hole PCB mounting using five PC pins
Applications
- Medical alarm systems requiring IEC60601-1-8 compliance
- Temperature and energy status indication in healthcare devices
- General purpose audio alerts in industrial control panels
Procurement Notes
Verify the specific manufacturing date code and RoHS compliance documentation upon order confirmation. Confirm availability status as supply constraints may affect immediate fulfillment. Ensure the receiving facility has appropriate handling procedures for electronic components. Cross-reference the full datasheet for detailed mechanical dimensions and electrical characteristics before finalizing integration into the design.
Selection Notes
Select this component when medical regulatory compliance is mandatory for the end application. The 3.3V to 5VDC operating range suits low-voltage digital logic interfaces. The 90dB output provides clear audible notification in moderate noise environments. Consider the 45mm form factor for spatial constraints on the printed circuit board layout.
Part Context
This buzzer belongs to the SBT5 series from Mallory Sonalert, specialized for medical and industrial audio signaling. The TM suffix typically denotes specific environmental or functional variations within the product line. It serves as a direct interface between microcontroller outputs and audible user feedback mechanisms in regulated industries.
Replacement Considerations
Consult official Mallory Sonalert substitution guides for verified equivalents. Ensure any replacement maintains IEC60601-1-8 certification if used in medical contexts. Verify that alternative parts match the 45mm diameter and 5-pin through-hole configuration for mechanical compatibility.
