CEP-2250

Overview

The CEP-2250 is a compact, surface-mount piezoelectric buzzer manufactured by Same Sky. It features an integrated driver circuit and operates on a DC voltage supply ranging from 3.0V to 12.0V. The device produces an acoustic output of 85dB at a distance of 10cm when driven at its nominal voltage of 5.0V. It utilizes a ceramic resonator element housed in a small form factor package measuring 22.0mm in length, 20.0mm in width, and 6.0mm in height. The unit is designed for direct connection to microcontroller GPIO pins or logic outputs without requiring external oscillators.

Feature Summary

• Integrated driver circuitry eliminates the need for external oscillator components
• Compact surface-mount design suitable for space-constrained PCB layouts
• Capable of generating high-intensity audible tones for alert applications

Applications

• Electronic appliance status indicators
• Portable medical device alarms
• Automotive interior warning systems

Procurement Notes

Verify the specific suffix code on the ordering part number to confirm the exact acoustic frequency and housing color options available. Confirm that the selected variant meets the required operating voltage range for the target system. Ensure the PCB footprint matches the manufacturer's recommended land pattern to guarantee proper mechanical stability and electrical contact during assembly.

Selection Notes

Select this component based on the required sound pressure level and physical dimensions. Evaluate the operating voltage compatibility with the host system's power rails. Consider the mounting orientation and thermal constraints during the layout phase. Verify that the acoustic performance meets the environmental noise requirements of the final product application.

Part Context

This component belongs to the family of active piezoelectric buzzers designed for simple tone generation. Unlike passive buzzers, it contains internal electronics to sustain vibration when DC power is applied. It serves as a cost-effective alternative to electromagnetic buzzers in modern consumer electronics where low profile and ease of integration are prioritized over variable frequency modulation capabilities.

Replacement Considerations

Cross-reference the pinout configuration and acoustic specifications with potential substitutes. Ensure any replacement part supports the same voltage range and mounting style. Verify that the replacement maintains equivalent sound pressure levels and frequency characteristics to preserve the intended user experience.
