PROJECTS UNLIMITED PCB Mount Omnidirectional Microphone 9.7mm

The PROJECTS UNLIMITED PCB Mount Omnidirectional Microphone is a high-quality, electret condenser microphone element engineered for direct integration into printed circuit board (PCB) designs. It offers super clarity and a distortion-free audio response, making it an ideal choice for capturing high-fidelity sound in a wide range of electronic applications. Its compact form factor and reliable performance ensure consistent audio pickup in space-constrained projects.

Featuring a true omnidirectional directivity pattern, this microphone captures sound uniformly from all directions. This characteristic is perfect for applications like conference phones, voice recorders, or environmental monitoring devices where audio needs to be gathered from a 360-degree field. The wide frequency response, from 20Hz to 20kHz, ensures faithful reproduction of the full range of audible sound, from deep bass to crisp highs.

Technical Performance

Designed for easy integration, the microphone operates on a low voltage supply ranging from 1.5VDC to 10VDC, with a maximum drain current of just 500µA, making it highly suitable for battery-powered and portable devices. It delivers a sensitivity of -46dB, providing a strong output signal relative to the sound pressure level. The device features a 2.2kohm impedance, ensuring stable performance and straightforward interfacing with standard audio amplifier circuits.
