CPT-2312-88T
Overview
The CPT-2312-88T is a through-hole piezo transducer designed for audible alert systems. As an externally driven device, it requires an oscillator or PWM signal to produce sound, offering flexibility in frequency control across its 1V to 30V operating range. It delivers a high sound pressure level of 88dB at 12V while maintaining a low current consumption of 5mA.
Why Choose This Part
This transducer features a wide operating voltage range of 1V to 30V and a wide operating temperature range from -40 to 85 degrees Celsius. Its 88dB output at 10cm provides clear audibility in noisy environments, and the two-pin through-hole package ensures secure mechanical mounting on PCBs.
Applications
Key Specifications
Getting Started
To drive this transducer, provide a square wave at the 2kHz resonant frequency using a microcontroller PWM output or a 555 timer circuit. Since it is a piezo device, ensure your driving circuit can handle the capacitive load and use a flyback diode or resistor if driving with high-voltage pulses.
