The CPT-9019S-SMT-TR is a surface-mount piezo transducer manufactured by CUI Inc. Designed for single-tone acoustic signaling, this component operates as an externally driven element requiring an external oscillator or microcontroller to generate the drive signal. It utilizes piezoelectric technology to convert electrical energy into mechanical sound waves.
Electrical characteristics center on a 4 kHz rated frequency with a typical sound pressure level of 65 dB measured at 10 cm under a 3 Vp-p square wave input. The device accepts a peak-to-peak voltage range up to 25 V, though its nominal operating voltage is 3 V. Typical current consumption is 5 mA during operation. Electrostatic capacity ranges from 8,400 pF to 15,600 pF when tested at 100 Hz and 1 V.
Mechanical construction features a 9.0 x 9.0 x 1.9 mm body with solder pad terminations suitable for automated surface mount assembly. The terminals are constructed from liquid crystal polymer with tin plating to ensure reliable reflow soldering compatibility. The acoustic port is located on the top surface, directing sound outward from the board plane.
Thermal ratings support industrial and commercial environments, with an operating temperature range of -30 °C to 70 °C and storage capability down to -40 °C. The component withstands peak reflow solder temperatures up to 260 °C for lead-free processes. It ships in tape and reel packaging containing 2,000 pieces per standard 330 mm diameter reel.
