Overview

The CPT-9019B-SMT-TR is a compact 9 mm square piezoelectric buzzer transducer designed for surface mount applications. It operates over a wide voltage range of 1 V to 25 V and is optimized for a 4.0 kHz resonant frequency to provide clear audible feedback in space-constrained designs.

Why Choose This Part

Its ultra-low 1.9 mm profile makes it ideal for modern slim electronics where vertical clearance is limited. The wide operating temperature range from -40 to +85 degrees Celsius ensures reliability in demanding environmental conditions.

Applications

Handheld Devices
Provides audible user alerts and button-press feedback in portable consumer electronics.
Medical Instrumentation
Integrated into compact diagnostic tools for status notifications and alarm signals.
Smart Home Sensors
Used in smoke detectors or security sensors where a small footprint and low profile are required.

Getting Started

To drive this transducer, an external oscillator circuit or a microcontroller PWM output is required at the 4.0 kHz resonant frequency. Ensure the PCB layout accounts for the 4 mm pin pitch and uses the recommended SMT solder reflow profile for the brass-tin plated terminals.

Also Consider

PS1240P02BT TDK Corporation - A popular 12.2 mm alternative for applications that can tolerate a larger footprint for higher sound pressure levels.
CMT-8540S-SMT-TR Same Sky - A magnetic transducer alternative that offers higher sound output at lower frequencies in a similar SMT package.
