CEM-1203(42)

Overview

The CEM-1203(42) is a through-hole magnetic buzzer transducer manufactured by Same Sky. It features a 12 mm round design with an 8.5 mm depth. The component operates at a frequency of 2048 Hz and requires a driving circuit. Electrical specifications include a rated voltage of 3.5 V, current consumption of 35 mA, and a sound pressure level of 85 dBA. The operating temperature range spans from -20°C to 60°C.

Feature Summary

• Externally driven magnetic transducer design requiring external drive circuitry
• Through-hole mounting configuration with PC pins for board integration
• Polyphenylene Oxide (PPO) housing material for structural integrity

Applications

• Audio indicators in electronic devices
• Alert systems requiring square wave output
• General purpose sound signaling components

Procurement Notes

Verify availability status as the component may be discontinued or subject to shipping restrictions in specific regions. Confirm that the required driving circuit is included in the system design, as this unit does not contain internal oscillators. Ensure mechanical fitment matches the 12 mm diameter and 8.5 mm depth constraints before procurement.

Selection Notes

Select this component when an externally driven magnetic buzzer is required for through-hole assembly. Consider the 3.5 V nominal voltage and 35 mA current draw for power budget calculations. Verify that the 85 dBA acoustic output meets the application's audibility requirements within the specified -20°C to 60°C operating temperature range.
