CEP-1130

Overview

The CEP-1130 is an externally driven piezo audio transducer buzzer manufactured by Same Sky. It features a 30.00 mm diameter and 7.5 mm depth, designed for through-hole mounting. The device operates at 10 V with a current draw of 10 mA, producing a sound pressure level of 90 dB at 10 V.

Feature Summary

• Externally driven piezoelectric operation
• Through-hole PCB mounting configuration
• Round acoustic design

Applications

• General purpose audible alarms
• Indicator signals in electronic devices
• Buzzer applications requiring external drive circuits

Procurement Notes

Verify the manufacturer designation as Same Sky (Formerly CUI Devices) to ensure component authenticity. Confirm that the specific part number CEP-1130 matches the required 10 V operating voltage and 90 dB acoustic output specifications for your design. Ensure compatibility with through-hole assembly processes.

Selection Notes

Select this component when an externally driven piezo element is required rather than an integrated oscillator type. Consider the 30 mm diameter and 7.5 mm depth for enclosure space constraints. Verify that the driving circuit can supply the necessary 10 mA current at 10 V to achieve the specified 90 dB output level.

Part Context

This component belongs to the audio transducer category within the Same Sky portfolio. It serves as a passive piezo element distinct from active buzzers containing internal oscillators. The product line focuses on providing reliable acoustic signaling solutions for various industrial and consumer electronics applications.

Replacement Considerations

Consult official datasheets for direct pin-compatible substitutes. Verify that any alternative maintains the same 30 mm diameter, 10 V rating, and through-hole mounting style to ensure mechanical and electrical compatibility.
