10 Knowles 6MM Miniature Omnidirectional Condenser Microphones -42±3 MB6022AWC-4

Description

3182ZC5D.02
New 10 Knowles Acoustics 6MM Miniature Omnidirectional Electret Condenser Microphones -42±3 Sensitivity, Part Number MB6022AWC-4.  Each bid quantity is for a Lot of Ten (10) Pieces.  You may bid / buy any number of lots, up to the total quantity available above.
These were purchased at an electronics supplier liquidation earlier this year, and they were brand new in the original factory boxes.  We packaged them in heavy Ziplok bags for resale.  Nice little microphones, with rubber housings for protection and noise reduction, and gold plated mini RF connectors.   It looks like the housing is designed to pop into a small hole in thin material, as they are slightly larger in front than the middle.
The manufacturer's part number (MB6022AWC-4) breaks down as follows:
M = ECM microphone type
B = Electret type
60 = Diameter of Microphone module (6.0 mm)
22= Height of Microphone (2.2 mm)
A = Directivity: A=Omnidirectional
W = Terminal Connection: W=mini-RF female connector
C = Capacitor Configuration: C=33&10pF
4 = ? Don't know. Possibly designates the rubber housing or the gold plated mini RF connector.
We located a datasheet for these (small PDF file):
