CMI-0955-03TH

Overview

The CMI-0955-03TH is a magnetic electromagnetic buzzer from Same Sky, designed for audible alert applications. It operates at a rated voltage of 3 VDC with a current draw of 30 mA. The device produces a sound pressure level of 80 dBA at 3V measured at 10 cm and functions at a frequency of 2.7 kHz. It features an internal driving circuit and utilizes through-hole solder pin termination. The physical dimensions are approximately 9.6 mm in diameter and 5 mm in height.

Feature Summary

Integrates an internal driving circuit for simplified interface requirements
Utilizes electromagnetic technology for reliable audio indication
Supports through-hole mounting for standard PCB assembly processes

Applications

Audible alert systems
Notification indicators
Electronic device status signaling

Procurement Notes

Verify the specific operating voltage rating of 3 VDC against the target circuit design to ensure compatibility. Confirm that the through-hole package dimensions align with the printed circuit board layout. Check RoHS compliance documentation for regulatory adherence. Ensure the 30 mA current consumption fits within the power budget of the driving source.

Selection Notes

Select this component when a low-profile, internally driven magnetic buzzer is required for 3 VDC systems. The 2.7 kHz frequency provides a distinct audible tone suitable for general alerts. Consider the through-hole form factor if surface-mount options are not feasible for the mechanical assembly constraints.

Part Context

This part belongs to the CMI series of audio indicators manufactured by Same Sky, formerly CUI Devices. The series offers various voltage and size options for different application needs. This specific model represents a compact solution for basic audible notification tasks in consumer and industrial electronics.

Replacement Considerations

Consult official manufacturer substitution guides for verified equivalents. Generic replacements may differ in acoustic output or electrical characteristics.
