Overview

The CPE-163 is an externally driven piezoelectric transducer designed for single-tone audible signaling. It requires an external peak-to-peak signal to produce sound, offering an output level of 80 dB at 10 Vp-p. This component features a compact 13 mm length and comes with custom wire leads for flexible mounting in various enclosures.

Why Choose This Part

With a rated current of only 10mA, this piezo transducer is highly efficient for battery-powered applications. Its wide operating voltage range up to 30V and broad temperature rating from -30 to +85 degrees C make it robust for various environmental conditions.

Applications

System Status Indicators
Providing audible feedback for user interface events or error states in handheld devices.
Timer and Alarm Alerts
Functioning as a low-current acoustic output for timing circuits or low-voltage security sensors.
Diagnostic Signaling
Emitting specific frequency tones to indicate successful power-on-self-test or hardware fault codes.

Getting Started

To drive this transducer, generate a square wave or PWM signal from a microcontroller using a driver circuit, such as a simple BJT or MOSFET switch. For maximum volume, target a 4,800 Hz square wave as specified in the datasheet performance metrics. Ensure the peak-to-peak voltage does not exceed the 30V maximum rating while maintaining sufficient current for the piezo element.
