The CPE-353 is a piezo buzzer indicator designed for audible alert applications in electronic equipment. It features wire leads with panel-mount tabs for easy installation and operates at a rated voltage of 12 Vdc with a rated frequency of 2.8 kHz, producing a slow pulse tone at 1.5 Hz. The device has a maximum current consumption of 8 mA at rated voltage and generates a sound pressure level of 81 dB at 30 cm. With an operating voltage range of 3 to 28 Vdc and operating temperature range of -30°C to +85°C, the CPE-353 is suitable for a wide variety of industrial and consumer applications requiring reliable audible indication. Its compact cylindrical design (Ø41.8 × 16.0 mm) and RoHS-compliant construction make it ideal for panel-mounted alarm and notification systems.
