CES-603318-24PM

Overview

The CES-603318-24PM is a compact, surface-mount electromagnetic buzzer manufactured by Same Sky. It operates at a nominal voltage of 3V DC and features a piezoelectric sounder element housed in a plastic enclosure with dimensions of 6.0mm x 3.3mm x 1.8mm. The device provides an acoustic output level of approximately 75dB at a distance of 10cm. It utilizes a passive driving mechanism requiring an external oscillator signal to generate sound. The component is designed for integration into space-constrained electronic assemblies where low profile and reliable audio indication are required.

Feature Summary

• Ultra-low profile design suitable for thin consumer electronics
• Surface-mount construction for automated assembly processes
• Passive operation mode allowing flexible frequency control via external drive signals

Applications

• Portable medical devices requiring audible alerts
• Smart home appliances with limited internal height clearance
• Wearable technology components needing compact audio feedback

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required mounting orientation and terminal configuration. Confirm that the passive nature of the buzzer aligns with the system's ability to provide the necessary oscillating drive signal. Check for any RoHS compliance documentation relevant to the specific production batch.

Selection Notes

Select this component when board space is severely restricted and a low-profile audible indicator is needed. Ensure the host circuit can supply the required 3V DC operating voltage and generate the appropriate frequency signal for activation. Consider the acoustic requirements relative to the 75dB output specification at 10cm distance.

Part Context

This part belongs to Same Sky's series of miniature surface-mount buzzers. It is engineered for high-volume manufacturing environments where consistent acoustic performance and mechanical stability are critical. The product line emphasizes miniaturization without compromising acoustic efficiency or electrical reliability under standard operating conditions.

Replacement Considerations

Consult official cross-reference lists for direct replacements. Verify that substitute parts match the 6.0x3.3x1.8mm footprint and 3V DC operating voltage. Ensure equivalent acoustic output levels and passive drive requirements are met before implementation.
