The CMC-2742PBJ-A is an omnidirectional electret condenser microphone designed for compact audio capture in consumer and industrial applications. It features a 6.0 mm diameter aluminum housing with gold-plated solder pins for reliable PCB integration, operating at a standard voltage of 2 Vdc with a maximum rating of 10 Vdc. The microphone delivers a sensitivity of -42 dB (typical) at 1 kHz and 1 Pa, with an output impedance of 2.2 kO and a frequency response range of 100 Hz to 20 kHz, achieving a signal-to-noise ratio of 58 dBA. Current consumption is minimal at 0.4 mA maximum, and the device operates reliably across -20°C to +70°C. This microphone is ideal for voice recording, communication devices, and audio sensing applications where space constraints and low power consumption are critical requirements.
