BMT1612H14-20

Overview

The BMT1612H14-20 is an externally driven magnetic buzzer transducer manufactured by BeStar Technologies, Inc. It operates at a nominal voltage of 12 V with a maximum current consumption of 40 mA. The device features a resonant frequency of 2.048 kHz and produces a sound pressure level of 85 dB measured at 6 V. Designed for through-hole mounting via PC pins, the unit measures 16 mm x 14 mm. It functions as a non-self-drive component and is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• Externally driven magnetic transducer design requiring external oscillator circuitry
• Through-hole PC pin termination for standard PCB integration
• Black housing construction suitable for industrial environments

Applications

• Industrial control panel signaling
• Appliance status indication
• General purpose electronic alert systems

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as LF or other codes may indicate different acoustic outputs or packaging configurations. Confirm that the application circuit provides the necessary external drive signal, as this is a non-self-drive transducer. Ensure the PCB layout accommodates the 16mm x 14mm footprint and through-hole pin spacing. Cross-reference datasheets for precise mechanical drawings before finalizing assembly designs.

Selection Notes

Select this component when a low-profile, high-reliability magnetic buzzer is required for 12 V systems. The 2.048 kHz frequency offers distinct audibility compared to lower-frequency alternatives. Consider the 85 dB output level against ambient noise requirements. Verify that the host system can supply the required 40 mA drive current without exceeding thermal limits in enclosed spaces.

Part Context

BeStar Technologies specializes in acoustic, haptic, and sensor components. This model belongs to their electromagnetic buzzer series, characterized by compact dimensions and robust performance. The product line focuses on providing custom solutions for complex acoustic problems, serving various electronics manufacturing sectors.

Replacement Considerations

Check for direct substitutes from BeStar with similar form factors, such as the BMT1612H14-52, noting differences in decibel ratings. Ensure any replacement maintains the 12 V nominal voltage and compatible resonant frequency to preserve system audio characteristics.
