KINGSTATE KPEG116 Piezo Audio Transducer 90dB SPL

The KINGSTATE KPEG116 Piezo Audio Transducer is a reliable, low-power component designed to generate clear, audible signals in a wide range of electronic applications. It produces a sound pressure level of 90dB SPL at a resonant frequency of 2kHz, providing a loud and distinct alert tone ideal for user interfaces, alarms, and status indicators.

Engineered for efficiency, it operates on a maximum supply voltage of 30V with a low maximum current draw of just 8mA, making it suitable for power-sensitive designs and battery-operated devices. Its robust construction allows it to perform reliably across a broad operating temperature range from -30°C to 85°C, ensuring consistent functionality in challenging environments.

Compact in design, it is simple to integrate into existing systems for applications such as electronic instrumentation, household appliances, and industrial equipment where an acoustic signal is required.
