Electret Microphone Capsule 9.7×4.5mm

The Omnidirectional Electret Microphone Capsule is a compact analog audio sensor designed for sound detection and voice capture in embedded systems and electronic projects. It features an electret condenser element with omnidirectional pickup, allowing it to detect sound from all directions with consistent sensitivity. Operating from a wide 1–10 V supply range with low current consumption, it provides reliable analog audio signals for amplification or processing circuits. Its small 9.7 mm diameter package with PC pin termination makes it suitable for integration into microphone modules, audio detectors, and voice-enabled prototypes.
