EK-29965-000

Microphones Overview

The EK-29965-000 is an analog electret condenser microphone manufactured by Knowles. It features an omnidirectional polar pattern and operates within a frequency range of 100 Hz to 10 kHz. The sensitivity is specified as -57 dB ±3 dB at 74 dB SPL. The device utilizes solder pads for mounting and has a side port location. Physical dimensions are 5.56 mm in length, 3.98 mm in width, and 2.21 mm in height.

Microphones Feature Summary

• Omnidirectional acoustic design for uniform sound capture
• Analog output signal generation via electret condenser technology
• Side-mounted port configuration for directional airflow management

Microphones Applications

• General purpose audio recording devices
• Voice recognition systems
• Consumer electronic audio input modules

Microphones Procurement Notes

Verify the specific revision level and RoHS compliance status against the latest manufacturer datasheet before integration. Confirm that the solder pad termination type matches the target PCB footprint requirements. Ensure environmental operating conditions align with the component's specified thermal and humidity limits for long-term reliability.

Microphones Selection Notes

Select this component when an omnidirectional response is required for ambient sound capture. The fixed sensitivity of -57 dB suits applications requiring moderate gain stages. Consider the physical profile of 2.21 mm height during enclosure design. Validate impedance matching with downstream preamplifiers to maintain signal integrity across the 100 Hz to 10 kHz bandwidth.

Microphones Part Context

This microphone belongs to Knowles' portfolio of analog acoustic sensors designed for compact consumer electronics. It represents a standard solution for voice input where size constraints limit larger microphone options. The product line emphasizes reliable performance in mass-produced audio devices requiring consistent frequency response.

Microphones Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-reference with other omnidirectional electret microphones only if electrical parameters and mechanical dimensions are strictly matched.
