Part Number System and Ordering Information
MICROPHONES – ECMs
Electret Condenser Microphones
Electret Condenser Microphones (ECM) are for general use in all electronic products requiring
a microphone. ECMs provide good acoustic performance and reliability under non-severe
environmental conditions.
Omni-Directional – 3 mm
Omni-Directional – 4 mm
Notes:
1. All sensitives are referenced at 1 kHz (1V/Pa)
2. Frequency graphs are typical. Contact manufacturer
corded and cordless phones, PDAs, notebooks, and mobile phones
Highly efficient electrical specifications
Industry standard sizes
Omni, Uni, and Noise Canceling Directivities
Integrated capacitors for RF filtering
