Data Sheet POM-5046P-C3310-R PUI Audios omnidirectional electret condenser microphones (ECMs) capture sound from all directions with a 360 polar pattern. Excellent for conference phone recording, these microphones are best suited for applications where the directionality of the acoustic source, with relation to the microphone, may be unknown or when placed centrally among multiple acoustic sources. Features: 6mm diameter 5mm height -46 dB sensitivity 50cm >55 dB signal-to-noise ratio Circular polar pattern to capture all sounds equally well regardless of placement Integrated 33pF and 10pF buzz-blocking capacitors reduce GSM noise Specifications Parameters Values Units Sensitivity (1 kHz 50cm) 0 dB=1V/Pa -46 3 dB Rated Voltage 2 VDC Output Impedance ( 1 kHz) 0.68 k Current consumption (3VS with 2.2 k RL) 500 A Signal-to-Noise Ratio (1kHz, 94 dB input, A-weighted) >55 dB Decreasing Voltage (2VS to 1.5VS) -3 dB Frequency Range ( 50cm, -10 dB) 20 ~ 20,000 Hz Operating Voltage Range 1 ~ 10 VDC Maximum SPL Input (THD<3%) 110 dB Directivity Omnidirectional - 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 This document contains data proprietary to PUI Audio Inc.
