Overview
The SBS12VMHMPPC is a piezoelectric buzzer from the Mallory Sonalert SBW series, designed for PCB mounting. It operates on a DC voltage range of 9 to 12 V with a current rating of 630 mA. The device produces a sound pressure level between 85 dB and 95 dB within a frequency range of 150 Hz to 4 kHz. Its physical dimensions are 44.45 mm in diameter and 15 mm in height, featuring solder terminals. The unit functions reliably within an operating temperature range of -30°C to +65°C.
Feature Summary
- Integrated internal drive circuitry for direct connection without external oscillators
- Cardiac-specific acoustic profile optimized for medical alert applications
- Robust construction suitable for industrial environments across wide temperature ranges
Applications
- Medical equipment alarm systems
- Industrial safety warning devices
- General audio indication circuits
Procurement Notes
Verify the specific acoustic output requirements against the 85-95 dB range before procurement. Confirm that the 630 mA current draw is supported by the target power supply. Ensure the PCB layout accommodates the 44.45 mm diameter footprint and solder terminal spacing. Check for RoHS compliance documentation if required by regional regulations.
Selection Notes
Select this component when a dedicated cardiac alert tone is required in a compact form factor. The integrated driver simplifies schematic design compared to passive buzzers. Consider the 15 mm height constraint for enclosure design. The wide operating temperature range supports deployment in uncontrolled environments where standard consumer-grade components might fail.
Part Context
This part belongs to the SBW series of piezoelectric buzzers manufactured by Mallory Sonalert Products Inc. The series is characterized by high reliability and integrated driving capabilities. These components are widely used in professional audio signaling applications requiring consistent performance and durability.
Replacement Considerations
Cross-reference with other SBW series variants for mechanical compatibility. Verify electrical parameters such as voltage and current ratings match the existing circuit design. Ensure the replacement maintains the same mounting style and terminal configuration.
