CMS-15116-SP

Speakers Overview

The CMS-15116-SP is a surface-mount piezoelectric buzzer manufactured by Same Sky. It features a rectangular form factor with dimensions of 15.0 mm in length, 11.0 mm in width, and 6.0 mm in height. The device operates at a nominal frequency of 2.3 kHz and produces a sound pressure level of 85 dB when driven by a 5.0 V DC signal at a distance of 10 cm. It utilizes a built-in oscillator for direct drive capability from logic outputs.

Speakers Feature Summary

• Integrated oscillator enables direct connection to microcontroller GPIO pins without external driving circuitry.
• Surface-mount design facilitates automated assembly and compact PCB integration.
• Rectangular housing provides structural stability and consistent acoustic projection.

Speakers Applications

• Consumer electronics audio alerts
• Industrial control panel indicators
• Medical device status signaling

Speakers Procurement Notes

Verify the specific suffix designation against the manufacturer's current datasheet to confirm exact terminal plating and lead availability. Ensure the operating voltage matches the system supply to prevent driver overload. Confirm mechanical mounting hole alignment with the PCB footprint before finalizing the bill of materials.

Speakers Selection Notes

Select this component when a low-profile, self-oscillating audible indicator is required for space-constrained designs. Compare the 85 dB SPL rating against ambient noise requirements to ensure audibility. Evaluate the 2.3 kHz tone frequency against user perception preferences for alert distinctiveness.

Speakers Part Context

This part belongs to the Same Sky CMS series of surface-mount buzzers. The series offers various frequencies and sound pressure levels within standardized rectangular footprints. The CMS-15116-SP represents a mid-range output option suitable for general-purpose notification tasks in commercial equipment.

Speakers Replacement Considerations

Cross-reference with other manufacturers' 15x11mm surface-mount buzzers having similar 2.3 kHz frequency and 85 dB SPL ratings. Verify pinout compatibility and thermal resistance characteristics during replacement analysis.
