SBT12M1PC

Overview

The SBT12M1PC is a piezoelectric buzzer from the Mallory Sonalert SBT series, designed for through-hole mounting. It operates on a DC input voltage range of 9 to 12 volts and draws a current between 46 and 150 mA. The device produces a continuous tone at a frequency of approximately 3 kHz with a sound pressure level of 95 dB. It features internal drive circuitry, allowing direct connection to power sources without external oscillators. The unit utilizes PC pin termination for secure board attachment.

Feature Summary

• Internal drive circuitry enables direct DC operation without external components
• Piezoelectric transducer technology ensures reliable acoustic output
• Through-hole PC pin termination provides robust mechanical mounting

Applications
