Overview
The BMT1612H14 is a passive electromagnetic buzzer manufactured by BeStar Technologies, Inc. It features a 16mm diameter and operates at a rated voltage of 12V DC with a current consumption of 40mA. The device produces a sound output level of 85dB measured at a distance of 10cm. Its resonant frequency is specified at 2.048kHz. The component utilizes through-hole PC pins for mounting and is designed to function within an operating temperature range of -40°C to 100°C.
Feature Summary
- Externally driven magnetic transducer design
- Passive operation requiring external drive signal
- Through-hole PC pin termination style
Applications
- White goods alarm systems
- Durables indicator alerts
- General purpose audible signaling
Procurement Notes
Verify the specific suffix code (e.g., LF, -20, -52) against your bill of materials, as these denote variations in packaging or acoustic performance. Confirm that the through-hole pin configuration matches your PCB layout requirements. Ensure the 12V DC rating aligns with your system power supply specifications before ordering.
Selection Notes
Select this model when a passive electromagnetic buzzer is required for 12V applications. The 85dB output is suitable for general alerting in consumer durables. Consider the -40°C to 100°C temperature range for environmental compatibility. Verify if the standard 16mm size fits the enclosure constraints compared to other series like the BMT1201H8.5F.
Part Context
This component belongs to the BMT series of electro-magnetic buzzers from BeStar Technologies. It is categorized under alarms, buzzers, and sirens. The product line serves North American customers and includes various voltage and size variants such as the BMT1612XH14 and BMT1612H14-20.
Replacement Considerations
The BMT1612H14-20 is a related variant offering similar electrical characteristics but may differ in packaging or specific acoustic testing conditions. Cross-reference datasheets to ensure pinout and mounting hole dimensions are identical before substituting.
