The PT-2038WQ is a direct-drive audio transducer designed to produce sound when driven by an external signal source. It has a resonant frequency of 3800 ± 500 Hz and delivers a minimum sound pressure level of 90 dB at 10 cm when operated at its rated voltage of 5.0 Vp-p. The component supports a maximum operating voltage of 30 Vp-p and has a current consumption of 5.0 mA or less. Lacking internal circuitry, this transducer offers design flexibility, making it suitable for various applications requiring customized audible alerts or indicators.
