CEM-1205C

Overview

The CEM-1205C is a magnetic audio indicator buzzer manufactured by Same Sky, formerly CUI Devices. It features a rated voltage of 5.0 Vdc and an operating voltage range of 4.0 to 7.0 Vdc. The component consumes a maximum current of 35 mA and produces a sound pressure level of at least 83 dB. This through-hole device is designed for audible signaling applications.

Feature Summary

• Magnetic transducer technology for reliable acoustic output
• Integrated driving circuit for simplified interface
• Through-hole mounting for standard PCB assembly

Applications

• Consumer electronics status indication
• Industrial control panel alarms
• Appliance operational feedback

Procurement Notes

Verify the obsolete status of the CEM-1205C before procurement planning. Confirm availability of direct substitutes such as the CEM-1205-IC. Ensure that replacement components meet all original electrical and mechanical specifications to maintain system compatibility and performance integrity during production transitions.

Selection Notes

Select this component only if legacy design compatibility is required. Evaluate alternative active buzzers or newer magnetic models from the same manufacturer for improved supply chain stability. Consider form factor constraints and voltage requirements when choosing between surface mount and through-hole variants in the product family.

Part Context

This part belongs to the CEM series of magnetic buzzers from Same Sky. The series includes various voltage ratings and mounting styles. The CEM-1205C specifically represents the 5V through-hole variant with integrated driving capabilities, distinguishing it from passive coils or surface-mount options within the broader portfolio.

Replacement Considerations

The CEM-1205-IC is listed as a direct substitute. Verify pinout compatibility and acoustic output levels. Check for any changes in terminal plating or housing material that might affect soldering or environmental resistance.
