CC09M04M16-2731

Overview

The Seltech CC09M04M16-2731 is a passive magnetic buzzer with a 9mm diameter and surface-mount solder pad package. 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 87dB at 3.6V and 10cm distance, with a resonant frequency of 2731Hz. Physical dimensions are approximately 9x12.3x4mm. It draws 100mA current.

Feature Summary

• Passive magnetic transducer design requiring external drive circuitry
• Surface-mount construction for automated PCB assembly
• Compact 9mm form factor suitable for space-constrained enclosures

Applications

• Electronic alarm systems
• Audible status indicators in consumer electronics
• Industrial control panel feedback

Procurement Notes

Verify the specific suffix 2731 to confirm the 2731Hz resonant frequency and 16 Ohm impedance. Ensure the passive type matches the driver circuit capabilities. Confirm surface-mount orientation and solder pad compatibility during integration.

Selection Notes

Select this component when a low-profile, passive acoustic indicator is required. The 3.6V rating suits battery-operated or low-voltage logic circuits. Verify that the driving circuit can supply sufficient current for the 16 Ohm load to achieve the specified acoustic output.

Part Context

This part belongs to Seltech's line of magnetic buzzers. It differs from active buzzers by lacking internal oscillators. The CC prefix typically denotes the series, while M indicates magnetic operation. SMD packaging distinguishes it from through-hole variants.

Replacement Considerations

Direct substitutes must match the 9mm diameter, 16 Ohm impedance, and 2731Hz frequency. Verify mechanical footprint compatibility for surface-mount pads. Ensure the replacement supports the 3.6V operating voltage without exceeding power limits.
