It complies with RoHS standards and utilizes PC pin termination for board mounting.
Feature Summary
- Generates a specific cardiac alarm tone for medical alerting
- Operates on low DC voltage supply ranges
- Complies with RoHS environmental standards
Applications
- Medical device cardiac alarms
- Hospital equipment audio indicators
- Patient monitoring systems
Procurement Notes
Verify the exact datasheet specifications against the manufacturer's official documentation before integration. Confirm that the 3.3-5VDC operating range aligns with your system power rails. Ensure the through-hole PC pin footprint matches your PCB layout requirements. Check for any specific medical certification updates required for your region.
Selection Notes
Select this component when a distinct cardiac alarm tone is required in compact medical electronics. The 90 dB output ensures audibility in noisy clinical environments. Verify compatibility with 3.3V or 5V logic levels. Consider the through-hole mounting style if surface-mount alternatives are unsuitable for mechanical stability.
Part Context
This part belongs to the SBT series of audio indicators from Mallory Sonalert. The series includes various tones such as general, failure, and drug-fluid alerts. The SBT5CMCMPPC specifically denotes the cardiac variant within this industrial-grade lineup designed for reliable performance in critical applications.
Replacement Considerations
Consult the official Mallory Sonalert substitution guide for verified equivalents. Cross-reference other SBT5 series variants only if the specific cardiac tone requirement can be relaxed. Ensure any substitute maintains the same voltage and acoustic specifications.
