Same Sky

Compact Electret Condenser Microphones

Same Sky's highly sensitive ECM microphone line offers models as small as 3 mm

Image of Same Sky Compact Electret Condenser MicrophonesUsed to convert sound into an electric signal, Same Sky's ECM microphones contain a permanent charge, eliminating the need for an external polarizing voltage. The models are housed in compact packages as small as 3 mm in diameter with depths as low as 1 mm. Featuring omnidirectional, unidirectional, and noise-canceling options in a range of configurations, these ECM microphones provide higher sensitivity ratings and signal-to-noise ratios, resulting in superior sound performance.

For easier prototyping and design testing, Same Sky's also offers an ECM microphone development kit consisting of four independent microphone evaluation circuits. (Please see below for more kit information)

Features
  • Diameters ranging from 3 mm to 9.7 mm
  • Depths as low as 1 mm
  • Sensitivity ratings from -54 dB to -24 dB
  • High signal-to-noise ratio, up to 72 dBA
  • Operating frequencies from 20 Hz to 20,000 Hz
  • Noise-canceling, unidirectional, and omnidirectional directivity offerings
  • Surface mount, terminal, solder pad, pin, or wire leads mounting configurations
