The CMP-5247TF-K is a noise-cancelling electret condenser microphone designed for compact audio capture applications. It features a 9.7 mm diameter aluminum housing with solder pad terminals, operating at a standard voltage of 1.5 Vdc with a maximum operating voltage of 10 Vdc. The microphone delivers a sensitivity of -47 dB (typical) at 1 kHz and 1 Pa, with an output impedance of 680 O and a frequency response range of 100 Hz to 20 kHz. It achieves a signal-to-noise ratio of 58 dBA and operates reliably across temperatures from -20°C to 70°C with a maximum current consumption of 0.5 mA. This compact, RoHS-compliant microphone is ideal for portable devices, voice recording, and noise-sensitive applications where space constraints and low power consumption are critical requirements.
