SBT12GLMCTPC

Overview

The SBT12GLMCTPC is an internally driven piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates within a voltage range of 9 to 12 VDC and draws a current between 15 and 25 mA. The device produces a sound pressure level of 85 dB at 9 V measured from a distance of 10 cm, with a resonant frequency of 2.075 kHz. Designed for through-hole mounting via PC pins, it functions reliably across a temperature range of -30°C to +65°C.

Feature Summary

• Internally driven piezoelectric technology for simplified circuit integration
• Through-hole PC pin termination for standard board mounting
• Compliant with IEC standards for industrial audio indicators

Applications

• Industrial control panel status indication
• Medical equipment alarm signaling
• General purpose audio alerts in electronic systems

Procurement Notes

Verify the specific suffix configuration against official Mallory Sonalert documentation to ensure correct acoustic output and mounting style. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary. Ensure the operating voltage matches the system requirements before procurement.

Selection Notes

Select this component when a reliable, internally driven piezo buzzer is required for through-hole assembly. The 85 dB output at 9 V provides adequate audibility for general industrial applications. Verify that the 2.075 kHz frequency aligns with the desired alert tone characteristics for the target environment.
