Key Audio Performance
Featuring a true omnidirectional directivity pattern, this microphone element picks up sound uniformly from all directions, providing consistent audio capture in diverse environments. It boasts an impressively wide frequency response range from 20Hz to 20kHz, ensuring it reproduces everything from deep bass tones to the highest treble notes with accuracy. With a sensitivity of -40dB and a 2.2kohm output impedance, it offers a strong, clean signal suitable for direct connection to amplifier inputs or analogue-to-digital converters.
Versatile Power & Integration
The element operates on a low voltage DC supply ranging from 1.5V to 10V, with a maximum drain current of just 500µA. This low power consumption makes it exceptionally suitable for battery-powered and portable devices, helping to extend operational life. Its robust construction and tight manufacturing tolerances (±3%) guarantee reliable and consistent performance across every unit.
Whether you're developing voice-activated devices, audio recording equipment, intercom systems, or IoT sensors, this microphone element provides the professional-grade audio foundation your project requires. Its combination,
