Overview
The SBT5TLHFPPC is a surface-mount piezoelectric buzzer from Mallory Sonalert, designed for medical applications. It operates within an IEC voltage range of 3.3 to 5 VDC and delivers a sound pressure level of 90 dB. The device features a high-frequency tone suitable for critical care alarms. It complies with RoHS standards and is packaged in tape-and-reel format for automated assembly.
Feature Summary
- Complies with IEC60601-1-8 medical alarm standards
- Surface-mount technology for PCB integration
- High-intensity acoustic output for clear signaling
Applications
- Patient monitoring systems
- Infusion pumps
- Ventilator alarm circuits
Procurement Notes
Verify the specific suffix 'PPC' against the manufacturer datasheet to confirm package type and reel configuration. Ensure the selected variant matches the required operating voltage range of 3.3V to 5VDC for compatibility with low-voltage medical control boards. Confirm RoHS compliance documentation is available for regulatory submission.
Selection Notes
Select this component when space constraints require a surface-mount solution rather than through-hole mounting. The 90 dB output is appropriate for environments requiring audible alerts without excessive noise pollution. Verify that the board layout supports the specific footprint dimensions associated with the SBT5 series to ensure proper mechanical retention.
Part Context
This part belongs to the SBT5 series of medical piezo buzzers. The series is characterized by its compliance with international medical safety standards and its suitability for compact electronic devices. Mallory Sonalert designs these components specifically for reliability in critical healthcare equipment where consistent acoustic performance is mandatory.
Replacement Considerations
Consult the official Mallory Sonalert substitution guide for direct equivalents. Cross-reference pinout and acoustic specifications if considering alternative manufacturers. No public substitute part numbers are confirmed in the provided data.
