MO064404-1

Microphones Overview

The MO064404-1 is an omnidirectional electret condenser microphone manufactured by DB Unlimited. It features a frequency response range of 50 Hz to 16 kHz and operates at a supply voltage of 4.5 V. The device has an impedance of 2.2 kOhms, a sensitivity of -44 dB, and utilizes solder pad termination for surface mount integration.

Microphones Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound capture
• Electret condenser transducer technology
• Surface mount solder pad termination style

Microphones Applications

• Audio input devices in consumer electronics
• Voice recognition systems
• General purpose sound detection modules

Microphones Procurement Notes

Verify the specific termination type against official documentation, as conflicting data exists between SMD/SMT and solder pad descriptions. Confirm the operating voltage specification matches the design requirements, noting variations between 2V and 4.5V references in available sources. Ensure the sensitivity rating aligns with system gain calculations before finalizing procurement.

Microphones Selection Notes

Select this component when an omnidirectional electret microphone with a wide frequency response up to 16 kHz is required. The 2.2 kOhm impedance and -44 dB sensitivity are suitable for standard audio interfaces. Verify physical mounting constraints regarding the termination style to ensure compatibility with the target PCB layout.

Microphones Part Context

This model belongs to the MO series of microphones from DB Unlimited, designed for compact audio applications. It serves as a general-purpose sound capture solution within the manufacturer's portfolio of electret condenser devices.

Microphones Replacement Considerations

MO064402-5: Similar omnidirectional electret microphone but with different sensitivity (-44 dBA) and potentially lower operating voltage (2V). Verify impedance and termination compatibility before substitution.
