Overview
The BMT1205XH9.5 is an externally driven magnetic buzzer manufactured by BeStar Technologies, Inc. It features a 12mm diameter and utilizes through-hole PC pins for mounting. The component operates within a voltage range of 4 to 6.5V with a supply current of 30mA. It produces a sound pressure level of 85dB at 5V measured from a distance of 10cm. The resonant frequency is specified at 2.3kHz. The device is designed to function reliably within an operating temperature range of -25°C to 80°C.
Feature Summary
- Externally driven magnetic transducer technology
- Through-hole mounting configuration with PC pins
- High sound pressure output capability
Applications
- Electronic equipment audio signaling
- Appliance status indication
- Industrial control panel alerts
Procurement Notes
Verify the specific suffix designation when ordering, as variants such as the -IC version differ in drive type and package. Confirm that the externally driven requirement matches the circuit design, as this model does not contain internal oscillation. Ensure the PCB layout accommodates the through-hole pin spacing and that the operating environment remains within the specified thermal limits.
Selection Notes
Select this component when an external oscillator circuit is available to drive the buzzer element. The 12mm form factor suits compact enclosures requiring moderate acoustic output. Consider the 30mA current draw against power budget constraints. Verify that the 2.3kHz frequency aligns with audible alert requirements and regulatory standards for the target application environment.
Part Context
BeStar Technologies specializes in acoustic and sensor components. This part belongs to their magnetic buzzer series, distinguished by the need for an external driver signal. It differs from internally driven models which integrate oscillation circuits directly into the package. The product line focuses on reliable electromechanical conversion for industrial and consumer electronics.
Replacement Considerations
Direct substitutes must match the 12mm diameter, through-hole pin configuration, and magnetic technology. Verify that alternative parts support the 4-6.5V operating range and similar current consumption. Cross-reference datasheets to ensure compatible mounting dimensions and electrical characteristics for seamless integration.
