SG-15E Electret Condenser Microphone Capsule (9.5 mm, Omnidirectional)

The SG-15E Electret Condenser Microphone is a compact audio input component designed to capture voice and ambient sound in electronic circuits. Its 9.5 mm capsule uses electret condenser technology and an integrated field effect transistor (FET) to provide an electrical audio signal for further amplification and processing. Its omnidirectional pickup pattern makes it suitable for voice input, sound detection, communication devices, and embedded audio applications.
