PROJECTS UNLIMITED 9.7mm PCB Mount Omnidirectional Microphone Element

The PROJECTS UNLIMITED 9.7mm PCB Mount Omnidirectional Microphone Element is an ultra-compact, high-performance audio transducer designed for direct integration onto printed circuit boards (PCBs). Its built-in mounting and connection points facilitate a streamlined assembly process, reducing design complexity and saving valuable space in electronic devices.

This microphone element delivers superb clarity with a distortion-free response, capturing audio with exceptional fidelity across a wide frequency range from 20Hz to 20kHz. The omnidirectional polar pattern ensures uniform sound pickup from all directions, making it a versatile choice for applications where the sound source is not fixed.

Key Features

Engineered for reliability and consistent performance, this microphone is built to exacting specifications. With a tight tolerance of ±3%, it guarantees dependable audio capture in every unit. The low power consumption, with a maximum drain current of just 500µA and an operating voltage range of 4.5 to 10VDC, makes it ideal for battery-powered and portable electronics where energy efficiency is crucial.

Technical Performance

The element boasts a sensitivity of -45dB, providing a strong signal for further amplification and processing. Its output impedance of 1kohm is well-suited for interfacing with common amplifier and ADC (Analogue-to-Digital Converter) input stages, ensuring easy integration into your audio signal chain. The robust construction ensures stable performance even in varied environmental conditions.

With its minimal footprint and professional-grade audio characteristics, this microphone element is the perfect solution for upgrading or creating compact audio recording devices, communication systems, and embedded sound detection modules.
