Overview

The BMS1813F-11C-08H4.5-BBS152 is a general-purpose speaker manufactured by BeStar Technologies, Inc. It features an 8 Ohm impedance and a rectangular top port design with dimensions of 18x13 mm. The component has a rated power handling capacity of 700 mW and a maximum power rating of 1 W. Its frequency response spans from 500 Hz to 12 kHz, with a self-resonant frequency of 850 Hz. The unit delivers a sound pressure level of 93 dB.

Feature Summary

• Rectangular form factor with top port configuration
• Lead-free and RoHS compliant construction
• General-purpose audio output capability

Applications

• Consumer electronics audio output
• Small appliance signaling
• Portable device speakers

Procurement Notes

Verify the specific suffix codes against official BeStar documentation to ensure exact dimensional and electrical compliance. Confirm RoHS status and lead-free requirements match project specifications. Cross-reference the 18x13 mm physical footprint with PCB layout constraints before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring a compact rectangular speaker with top porting. Ensure the system can handle the 700 mW rated power and 8 Ohm impedance. Verify that the 500 Hz to 12 kHz frequency range meets the required audio performance standards for the intended use case.

Part Context

This part belongs to the BeStar Technologies general-purpose speaker lineup. It is designed for integration into small electronic devices where space is limited. The rectangular shape allows for efficient packing in tight enclosures compared to circular alternatives.

Replacement Considerations

Check for direct substitutes with identical 18x13 mm dimensions and 8 Ohm impedance. Ensure replacement parts maintain the same top port orientation and 93 dB sensitivity to preserve acoustic performance.
