CMI-9650C-030

Overview

The CMI-9650C-030 is an internally driven magnetic electromagnetic buzzer manufactured by Same Sky. It operates at a rated voltage of 3 VDC with a current consumption of 15 mA. The device produces a sound pressure level of 78 dBA at a frequency of 2.85 kHz. It features wire leads for through-hole mounting and has a circular body diameter of 9.6 mm.

Feature Summary

• Internally driven magnetic design for simplified circuit integration
• Electromagnetic transducer technology for audio indication
• Wire lead termination for flexible board connection

Applications

• General purpose electronic equipment status indicators
• Appliance audible alerts
• Industrial control panel signaling

Procurement Notes

Verify the specific electrical parameters against the official Same Sky datasheet before finalizing the design. Confirm that the wire lead configuration matches the target PCB layout requirements. Ensure the operating voltage range aligns with the system power supply to maintain optimal acoustic performance and longevity.

Selection Notes

Select this component when a low-profile, internally driven buzzer with wire leads is required. The 3 VDC rating suits battery-powered or low-voltage logic circuits. Compare the 78 dBA output against environmental noise levels to ensure adequate audibility for the intended application scenario.

Part Context

This part belongs to the CMI series of audio indicators from Same Sky. The series includes various voltage ratings and form factors, such as surface mount and different drive types. The CMI-9650C-030 specifically addresses applications requiring a 3 VDC operated electromagnetic buzzer with external wiring.

Replacement Considerations

Direct substitutes include other 3 VDC internally driven magnetic buzzers with similar dimensions and acoustic output. Verify pinout compatibility and mounting hole spacing if replacing in existing assemblies. Check for equivalent RoHS compliance and moisture sensitivity levels.
