Data Sheet

POM-5042P-C3310-R

PUI Audio’s 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

•

-42 dB sensitivity @ 50cm

•

>60 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
