• Analog output type suitable for direct integration into standard audio circuits
• Boom-style form factor with wire lead termination for flexible mounting

Microphones Applications

• Headset microphone assemblies
• Communication devices requiring noise reduction
• Voice input systems for industrial or consumer electronics

Microphones Procurement Notes

Verify the specific impedance value (2.2 kΩ) and current rating (300 uA) against your circuit design requirements. Confirm the mechanical dimensions, particularly the 160 mm cable length and 2.7 mm connector diameter, to ensure proper fitment. Check RoHS compliance status if required by your manufacturing standards. Ensure the operating voltage range of 1.3 V to 10 V matches your power supply.

Microphones Selection Notes

Select this component when a noise-canceling boom microphone is required for analog audio input. Consider the 300 Hz to 4 kHz frequency response for voice-centric applications. Evaluate the -59 dB sensitivity level against your system's gain requirements. The 2.2 kΩ impedance should be compatible with your pre-amplifier input stage. Verify the physical constraints of the 160 mm cable length in your final product design.
