Alarms, Buzzers, And Sirens Applications

• Consumer electronics notification systems
• Industrial device alerting
• Portable equipment signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix 'B' against the manufacturer's current datasheet to confirm exact mechanical dimensions and terminal configuration, as suffixes often denote packaging or minor physical variations. Ensure the external driver circuit can supply the required 120 mA peak current at 3 V without exceeding thermal limits. Confirm that the 3.1 kHz resonant frequency aligns with the target application's acoustic requirements.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a low-profile, surface-mount audible indicator is required for battery-operated devices due to its 3 V operation. The 80 dB output level is suitable for general alerts in moderate noise environments. Consider the 5.5 x 5.5 mm footprint for PCB space constraints. Verify compatibility with automated pick-and-place processes if high-volume manufacturing is planned.

Alarms, Buzzers, And Sirens Part Context

This part belongs to Challenge Electronics' series of electromagnetic transducers designed for compact electronic assemblies. The CT05E series utilizes a magnetic drive mechanism to generate sound efficiently. These components are typically used where size and power consumption are critical factors in the design of portable and embedded systems requiring audible feedback.
