CEP-1153

Overview

The CEP-1153 is an externally driven piezoelectric transducer manufactured by Same Sky. It operates at a nominal voltage of 10 V with a current consumption of 7 mA. The device generates an acoustic output of 82 dB measured at a distance of 10 cm. Its resonant frequency is 4 kHz, and it supports a maximum operating voltage of 30 V peak-to-peak. The component utilizes through-hole PC pins for mounting.

Feature Summary

• Externally driven piezoelectric design
• Through-hole PC pin termination
• Wide operating temperature range

Applications

• Alarm systems
• Audible notification devices
• Electronic warning circuits

Procurement Notes

Verify the specific datasheet revision when sourcing this component, as manufacturer documentation indicates potential updates to specifications or materials over time. Confirm that the external drive circuitry matches the 10 V nominal requirement and 7 mA current draw to ensure proper operation. Ensure the PCB layout accommodates the through-hole pin configuration and spatial requirements for the transducer body.

Selection Notes

Select this component when an externally driven piezo solution is required rather than an integrated active buzzer. The 4 kHz frequency provides a distinct audible tone suitable for alarms. Consider the 82 dB sound pressure level for environmental noise conditions. Verify that the application can provide the necessary external square wave signal to drive the piezo element effectively.

Part Context

This part belongs to the audio transducer category within Same Sky's portfolio. It serves as a passive piezo element requiring external excitation. This distinguishes it from self-exciting buzzers that contain internal oscillators. It is designed for integration into custom electronic assemblies where drive circuit control is preferred.

Replacement Considerations
