Overview
The SBT5VMHSPPC is a ventilation melody buzzer manufactured by Mallory Sonalert Products Inc. It features internal drive circuitry and accepts DC input within a voltage range of 3.3 to 5 VDC. The device produces a sound pressure level of 90 dB and is designed for through-hole mounting with PC pins. It complies with IEC standards and holds RoHS certification. The unit operates as an audio indicator suitable for industrial applications requiring specific melodic alerts.
Feature Summary
- Generates a ventilation melody tone using internal drive electronics
- Complies with IEC standards for industrial audio indicators
- Supports through-hole installation via PC pin termination
- Certified compliant with RoHS environmental directives
Applications
- Industrial panel alarm systems
- Medical equipment status indication
- Transportation vehicle monitoring interfaces
Procurement Notes
Verify the exact suffix configuration against the manufacturer's current datasheet before ordering, as suffixes define specific acoustic and electrical characteristics. Confirm that the ventilation melody variant matches the intended application requirements. Ensure compatibility with the target PCB layout regarding through-hole spacing and pin dimensions. Cross-reference the IEC compliance documentation if required for regulatory adherence in your specific region or industry sector.
Selection Notes
Select this component when a distinct melodic alert is required rather than a continuous tone. The 90 dB output ensures audibility in moderately noisy environments. Verify that the 3.3-5 VDC operating range aligns with the system power supply. Consider the physical dimensions and mounting style to ensure fit within the enclosure design constraints.
Part Context
This part belongs to the SBT series of industrial-grade audio indicators from Mallory Sonalert. The series is characterized by robust construction and compliance with international safety standards. These devices are engineered for reliability in demanding operational conditions across various sectors including healthcare and manufacturing.
Replacement Considerations
Consult the official Mallory Sonalert substitution guide for direct equivalents. Verify that any substitute maintains the same ventilation melody output and voltage specifications. Ensure mechanical footprint compatibility for existing PCB designs.
