CPT-1203-78-SMT-TR
Overview
The CPT-1203-78-SMT-TR is a surface-mount piezo buzzer transducer designed for audible alert applications requiring a small footprint. As an externally driven transducer, it requires an external oscillator circuit or microcontroller PWM signal to generate sound at its 4kHz resonant frequency.
Why Choose This Part
This transducer offers a wide operating voltage range from 1V up to 25V, providing flexibility for different power rail designs. Its low-profile surface-mount package with side porting allows for streamlined automated assembly and localized sound direction in tight enclosures.
Applications
Key Specifications
Getting Started
To operate this device, provide a square wave or peak-to-peak signal at the rated 4kHz frequency using a microcontroller PWM output and a switching transistor. Ensure the driving circuit can handle the 5mA supply current and verify the side port is not obstructed by the enclosure during mechanical design.
