CSS-73B16K-SMT

Alarms, Buzzers, And Sirens Overview

The CSS-73B16K-SMT is an externally driven magnetic transducer designed for surface mount technology (SMT) applications. It features a compact form factor with dimensions of 8.5 mm, suitable for space-constrained PCB layouts. The component operates at a nominal voltage of 3.6 V and draws a current of 100 mA. It produces a sound pressure level of 87 dB when measured at 10 cm distance under rated conditions. The operating frequency is specified at 2.73 kHz, providing a distinct audible tone. Termination is achieved via solder pads compatible with standard reflow processes.

Alarms, Buzzers, And Sirens Feature Summary

• Externally driven magnetic transducer design
• Surface mount termination for automated assembly
• Compact 8.5 mm footprint

Alarms, Buzzers, And Sirens Applications

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix requirements for tape and reel packaging if high-volume manufacturing is intended. Confirm that the driving circuit can supply the required 100 mA current to ensure stable operation. Check for any recent product change notifications regarding material composition or acoustic performance updates from the manufacturer.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a magnetic buzzer with SMT compatibility is required. Ensure the application environment stays within the -30°C to +70°C operating temperature range. Compare against piezoelectric alternatives if lower power consumption is critical, as this magnetic type requires higher drive current.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Same Sky audio transducer family, formerly associated with CUI Devices. It serves as a direct replacement for legacy through-hole magnetic buzzers in modern surface-mount designs. The series offers various voltage and acoustic output options to suit different alert intensity requirements.

Alarms, Buzzers, And Sirens Replacement Considerations

Check pinout compatibility with existing footprints. Verify that the new drive signal matches the 2.73 kHz resonant frequency for optimal acoustic output.
