The GMI4013S-2C46DB with Electret Condenser Microphone SMD RoHS is an ultra-compact surface-mount device (SMD), manufactured by INGHAi, that is specifically designed for recording and transmitting voice as well as acoustic signals in audio equipment, electronic instruments, and other electrical devices. This component features a high fidelity electret condenser microphone with an integrated amplifier, allowing for high-sensitivity audio capture at low distortion levels and low power consumption, and is compliant with the RoHS directive from the European Union. It also contains an adjustable low-cut filter that can be accessed through an external circuit, giving it the flexibility to produce different audio recordings. The device is constructed using reliable SMD technology and is ideal for applications where space is limited. Additionally, it is provided with an ESD protection circuit to protect against transient voltage.
