Overview
The SBT12GLCMPPC is an internally driven piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates within a voltage range of 3 to 12 VDC and produces a sound pressure level of 85 dB at 9 VDC measured at a distance of 10 cm. The device features a resonant frequency of approximately 2.5 kHz and draws between 15 and 20 mA during operation. It utilizes through-hole PC pin termination for PCB mounting and functions reliably across an operating temperature range of -30°C to +65°C.
Feature Summary
- Internally driven piezoelectric design eliminates the need for external oscillators
- Through-hole PC pin construction facilitates standard printed circuit board integration
- Robust performance across a wide industrial temperature spectrum
Applications
- Industrial control panel audio alerts
- Medical equipment status indicators
- Consumer appliance operational feedback
Procurement Notes
Verify the specific suffix configuration against official Mallory Sonalert documentation to ensure correct acoustic and electrical characteristics. Confirm that the through-hole package dimensions align with the target PCB layout. Ensure the selected unit meets the required environmental specifications for the intended deployment zone.
Selection Notes
Select this component when an integrated, self-oscillating audible alert is required without complex driver circuitry. The 85 dB output provides clear indication in moderate noise environments. Verify that the 15-20 mA current draw is compatible with the host system's power supply capabilities and logic levels.
Part Context
This part belongs to the Mallory Sonalert SBT series of piezoelectric buzzers. These devices are engineered for reliable audio signaling in electronic systems. The series offers various voltage and acoustic options to suit diverse application requirements while maintaining consistent build quality and performance standards.
Replacement Considerations
Consult official Mallory Sonalert substitution guides for verified equivalents. Ensure any replacement matches the 44.45 mm diameter, 2.5 kHz frequency, and 85 dB SPL specifications. Verify compatibility with existing PCB mounting holes and electrical interface requirements.
