Overview
The SBT5VMCMPPC is a board-mount piezoelectric buzzer manufactured by Mallory Sonalert. It operates within a voltage range of 3.3 to 5 VDC and delivers a sound pressure level of 85 dB at 3.3V measured at 10 cm. The device features PC pin termination for through-hole mounting and has a maximum seated height of 14.00 mm with a diameter of 44.45 mm. Designed for ventilation applications, it draws current between 15 and 40 mA.
Feature Summary
- Internally driven piezoelectric technology for reliable audio signaling
- Through-hole PC pin termination for standard PCB integration
- Compact cylindrical housing suitable for constrained panel spaces
Applications
- Ventilation system status indicators
- HVAC equipment alarm signaling
- Industrial control panel audio alerts
Procurement Notes
Verify the specific suffix against official Mallory Sonalert documentation to confirm electrical characteristics and acoustic output. Confirm RoHS compliance status directly from the manufacturer datasheet before procurement. Ensure the operating voltage aligns with the 3.3-5 VDC specification to prevent performance deviation or component damage.
Selection Notes
Select this component when a low-profile, internally driven piezo buzzer is required for ventilation or HVAC systems. The 85 dB output provides clear audible indication in moderate noise environments. Verify that the 44.45 mm diameter fits the available panel cutout and that the 14.00 mm height accommodates the enclosure depth constraints.
Part Context
This part belongs to the SBT series of board-mount audio indicators from Mallory Sonalert. These devices are engineered for industrial and commercial applications requiring robust, long-lasting audio signaling. The series offers various acoustic profiles tailored for specific operational needs such as general alerting or specialized medical and industrial warnings.
Replacement Considerations
Consult Mallory Sonalert technical support for verified cross-reference part numbers. Ensure any substitute matches the 3.3-5 VDC operating range, 85 dB SPL requirement, and 44.45 mm form factor.
