Overview

The PB-2712PQ is an 8 Ohm general-purpose speaker from Mallory Sonalert, designed for audio signaling in electronic devices. It features a compact 30mm round form factor with PC pin termination for direct mounting on printed circuit boards. The unit provides a sound pressure level of 85 dBA and is optimized for a frequency range between 1.05 kHz and 1.45 kHz.

Why Choose This Part

The PC pin termination allows for secure and cost-effective through-hole PCB mounting without manual wiring. With an 85 dB efficiency rating and a 200 mW power rating, it provides clear audibility in a compact 1.18 inch diameter package.

Applications

Audible Status Indicators
Ideal for providing user feedback in industrial control panels or consumer appliances through simple tones.
Alert Systems
Used in security panels and safety monitors to provide local acoustic warnings.
Diagnostic Beepers
Integrated into embedded systems for POST (Power-On Self-Test) error codes or operational status signals.

Getting Started

When designing the driver circuit, ensure the maximum power does not exceed 200 mW into the 8 Ohm load. Use a simple transistor-driven circuit or a low-power audio amplifier to feed the PC pins, keeping the signal within the 1.05 kHz to 1.45 kHz range for optimal acoustic performance.
