Overview
The BSP1109-05H1.7 is an externally driven piezoelectric buzzer manufactured by BeStar Technologies, Inc., designed for surface-mount assembly. It operates at a rated voltage of 5V with a supply current of 1mA. The component features a resonant frequency of 4.1kHz and delivers a sound pressure level of 70dB measured at a distance of 10cm under 5V excitation. The physical dimensions are specified as 11x9mm, utilizing solder tabs for connection.
Feature Summary
- Externally driven transducer architecture requiring external driver circuitry
- Surface mount package configuration with solder tab termination
- Piezoelectric acoustic generation mechanism
Applications
- Electronic device status indication
- Audible alarm systems
- Consumer electronics feedback signals
Procurement Notes
Verify the specific ordering suffix to ensure compliance with RoHS requirements and lead-free specifications. Confirm that the external driver circuitry matches the 5V operating voltage and 1mA current draw parameters. Ensure storage conditions remain within -10 to +40°C and 15 to 85% relative humidity to maintain shelf life integrity before installation.
Selection Notes
Select this component when a low-profile surface-mount piezo buzzer is required for compact designs. The 5V rating suits standard logic-level interfaces. Consider the 70dB output level against ambient noise requirements. Verify that the external drive capability aligns with the system's microcontroller or dedicated driver IC outputs.
Part Context
This part belongs to BeStar Technologies' range of acoustic components, which includes buzzers, haptic actuators, and sensors. The BSP series typically offers various form factors and electrical ratings. This specific model represents a standardized surface-mount solution for general-purpose audible signaling in portable and fixed electronic equipment.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 5V rating, 4.1kHz frequency, and 11x9mm footprint with compatible external drive capabilities.
