CST-911RP-A

Alarms, Buzzers, And Sirens Overview

The CST-911RP-A is a magnetic audio transducer buzzer manufactured by Same Sky. It operates at a rated voltage of 1.5 V with a current consumption of 80 mA. The device produces a sound pressure level of 85 dB measured at 10 cm distance and functions at a resonant frequency of 2.73 kHz. It utilizes through-hole PC pin termination for mounting.

Alarms, Buzzers, And Sirens Feature Summary

• Externally driven magnetic transducer design
• Side port acoustic output configuration
• Through-hole PC pin termination style

Alarms, Buzzers, And Sirens Applications

• General purpose audible alerting systems
• Electronic equipment status indication
• Consumer appliance signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix 'RP' to confirm side-port orientation and through-hole pin configuration. Ensure the driving circuit provides the required 1.5 V DC supply and can handle the 80 mA current draw. Confirm mechanical clearance for the 9 mm diameter housing and verify that the 2.73 kHz frequency matches the application requirements.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a low-voltage, externally driven magnetic buzzer is required. The 1.5 V rating suits battery-powered or low-voltage logic circuits. The through-hole format is appropriate for standard PCB assembly processes where surface-mount options are not feasible.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Same Sky magnetic buzzer family, formerly produced under the CUI Devices brand. It represents a standard round form factor transducer designed for cost-effective audible notification in various electronic assemblies.

Alarms, Buzzers, And Sirens Replacement Considerations

Check for direct substitutes within the Same Sky CST series that share the 9 mm diameter and 1.5 V rating. Verify that any replacement maintains the same external drive requirement and through-hole pin spacing.
