Overview
The SBT12GMHFPPC is an internally driven piezoelectric buzzer from Mallory Sonalert Products Inc. designed for through-hole mounting via PC pins. It operates on a DC voltage range of 9 to 12V and draws between 15 and 25mA. The device produces a general melody tone at a frequency of 2.075kHz with a sound pressure level of 85dB measured at 9V and 10cm distance.
Feature Summary
- Internally driven piezoelectric technology
- Through-hole PC pin termination
- General melody output mode
Applications
- Industrial equipment status indication
- Medical device audio alerts
- Consumer appliance signaling
Procurement Notes
Verify the specific suffix configuration against official Mallory documentation to ensure correct terminal type and acoustic characteristics. Confirm RoHS compliance status and environmental certifications required for the target application region before finalizing procurement orders.
Selection Notes
Select this component when a general melody alert is required for panel or board-mounted applications using standard through-hole assembly processes. Ensure the operating voltage aligns with the 9-12V DC specification and that the 85dB SPL meets audibility requirements at the intended measurement distance.
Part Context
This part belongs to the SBT series of industrial-grade audio indicators. It utilizes piezoelectric transducer technology to generate audible signals without external drivers, simplifying circuit design for alarm and notification systems in various electronic devices.
Replacement Considerations
Consult official Mallory Sonalert cross-reference guides for verified substitutes. Direct replacements must match the through-hole PC pin form factor, 9-12V DC operating range, and general melody acoustic profile.
