The CPT-1625-80-SMT-TR is a surface-mount piezo buzzer transducer designed for audio signaling applications requiring external drive circuitry. It delivers a minimum sound pressure level of 80 dB at 10 cm when operated at rated voltage with a 4,100 Hz square wave signal, making it suitable for alarm and notification systems. The device operates across a voltage range of 1 to 25 Vp-p, with a rated voltage of 5 Vp-p and maximum current consumption of 3 mA at rated conditions. Its compact dimensions of 13.0 × 13.0 × 2.5 mm and low weight of 0.5 g enable integration into space-constrained applications, while the LCP material housing with tin-plated brass terminals ensures durability and reliable soldering. The transducer maintains stable performance across an operating temperature range of -40°C to +85°C, making it ideal for consumer electronics, industrial equipment, and portable devices requiring audible feedback.
