CC09M04M16-2000

Overview

The Seltech CC09M04M16-2000 is a passive magnetic buzzer with a 9mm diameter and 12.3mm length. It operates at a rated voltage of 3.6V DC and features an impedance of 16 Ohms. The device produces a sound pressure level of 60dB at 10cm distance when driven by a 4V signal. It is designed for surface mount technology (SMD) assembly using solder pads.

Feature Summary

• Passive magnetic transduction mechanism
• Surface mount compatible construction
• Compact cylindrical form factor

Applications

• Electronic alarm systems
• Audible status indicators
• Consumer appliance signaling

Procurement Notes

Verify the specific suffix code to ensure correct acoustic output specifications, as variants like the -2731 differ in decibel rating. Confirm passive operation requirements against active alternatives. Ensure SMD footprint compatibility with PCB design constraints before ordering.

Selection Notes

Select this component for applications requiring low-profile audible alerts where passive drive circuits are utilized. Consider the 16 Ohm impedance for driver circuit matching. Evaluate the 60dB SPL against ambient noise levels to ensure adequate audibility for the intended use case.

Part Context

This part belongs to Seltech's line of miniature magnetic buzzers. It shares the 9mm diameter series with other models but differs in acoustic performance based on its specific suffix designation. It serves as a cost-effective solution for basic audio indication needs.

Replacement Considerations

The CC09M04M16-2731 is a verified substitute within the same series, offering higher acoustic output. Verify that the increased sound pressure level does not exceed regulatory limits or cause user discomfort in the final application environment.
