The CPI-2316-85T is a piezo buzzer indicator designed for audible alarm and notification applications. It features an internally driven circuit that operates at a rated voltage of 12 Vdc with an operating range of 3 to 20 Vdc, consuming a maximum of 10 mA at rated voltage. The buzzer produces a single tone at a rated frequency of 3,000 Hz (ranging from 2,500 to 3,500 Hz) and generates a sound pressure level of 85 dB at 30 cm. With a compact through-hole design measuring Ø23 × 16 mm and constructed from ABS material with tin-plated copper terminals, it operates reliably across -20°C to +60°C. This buzzer is ideal for embedded systems, alarm circuits, and notification devices requiring a compact, cost-effective audible indicator.
