Data Sheet

PNM-3550L-C3310-R

PUI Audio’s noise-canceling microphones are designed with dipole inlets on the

back of the microphone capsule to reduce background noise from wind and the

road for the clearest possible pickup of a user’s voice—especially when used in

automotive applications.

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

-50 dB sensitivity @ 50cm

>52 dB signal-to-noise ratio

Reduces the effect of wind and road noise

Integrated 33pF and 10pF buzz-blocking capacitors reduce GSM noise
