CMI-9655S-SMT-TR

Overview

The CMI-9655S-SMT-TR is a magnetic buzzer manufactured by Same Sky, designed for surface mount technology applications. It operates at a rated voltage of 5 V with a supply current of 30 mA and produces a sound pressure level of 80 dB at 5V measured at 10cm distance. The device functions at a frequency of 2.7 kHz and supports an input voltage range of 4 to 7 V. Its physical dimensions are 9.60 mm x 9.60 mm with a maximum height of 5.30 mm. The component features internal drive circuitry, top porting, and is rated for operation between -40°C and 85°C.

Feature Summary

• Features integrated internal drive circuitry for simplified system integration without external drivers.
• Utilizes magnetic transducer technology to generate audible alerts efficiently.
• Designed for surface mount installation with top-porting for direct sound projection.

Applications

• Electronic indicators in consumer appliances
• Audio alerts in medical devices
• Status signaling in industrial control panels

Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging when sourcing components. Confirm RoHS compliance status and MSL rating requirements against project specifications. Ensure the 5V rated voltage aligns with target circuit designs. Check datasheet revisions for any marking changes or dimensional updates prior to final procurement decisions.

Selection Notes

Select this component for applications requiring compact surface mount audio indication with low profile constraints. The 9.60 mm square footprint suits dense PCB layouts. Internal drive capability reduces bill of materials complexity compared to passive buzzers. Verify thermal management needs within the -40°C to 85°C operating range for the intended environment.
