The frequency response of the microphone is exceptionally flat when placed 2.54cm from the acoustic source, but rolls-off at 2 to 5 dB/octave when placed 50cm away from the acoustic source. Features:

  • 6mm diameter
  • 3.5mm height
  • -46 dB sensitivity @ 50cm
  • >55 dB signal-to-noise ratio
  • Reduces the effect of wind and road noise
  • Integrated 33pF and 10pF buzz-blocking capacitors reduce GSM noise Specifications Parameters Values Units Sensitivity (1 kHz @ 50cm) 0 dB=1V/Pa -46 ±4 dB Rated Voltage 2 VDC Output Impedance (@ 1 kHz) 2.2 kΩ Current consumption (3VS with 2.2 kΩ RL) 500 µA Signal-to-Noise Ratio (1kHz, 94 dB input, A-weighted) >55 dB Decreasing Voltage (2VS to 1.5VS) -3 dB Frequency Range (@ 2.54cm) 20 ~ 20,000 Hz Frequency Range (@ 50cm, -10 dB) 250 ~ 20,000 Hz Operating Voltage Range 1 ~ 10 VDC Maximum SPL Input (THD<3%) 110 dB Directivity Dipole - Operating Temperature -20 ~ +60 °C Storage Temperature -40 ~ +70 °C Weight <0.3 Grams

PUI Audio, Inc., 3541 Stop Eight Road, Dayton, OH 45414 Tel: (937) 415-5901 Fax: (937) 415-5925 Microphone Handling Precautions High temperature and/or static electricity may damage microphones. To ensure careful handling, we suggest following these precautions:

  • Ensure the power rating of the soldering iron is below 90 watts
  • The temperature of the soldering iron must be limited to 360°C ±10°C (680°F ±50°F)
  • Soldering duration for each terminal shall be at or under 2 seconds
  • If practical, use a metal fixture to hold the microphone in-place and to act as a heatsink. A fixture should have appropriate diameter holes drilled through the entire fixture to prevent pressure from being placed on the diaphragm (as below) Packaging
