EK-23115-000

Microphones Overview

The EK-23115-000 is an electret condenser microphone manufactured by Knowles. It features a rectangular surface-mount package with dimensions of 5.56 x 3.98 x 2.21 mm. The device provides analog output and exhibits omnidirectional acoustic sensitivity. Key electrical specifications include a sensitivity of -52.5 dB ±2 dB at 74 dB SPL. It utilizes a side-port design for sound intake.

Microphones Feature Summary

• Omnidirectional polar pattern for uniform sound capture from all directions
• Electret condenser transducer technology for analog audio signal generation
• Compact rectangular surface-mount form factor suitable for space-constrained designs

Microphones Applications

• Consumer electronics requiring compact audio input
• Portable communication devices
• Voice recognition systems

Microphones Procurement Notes

Verify the manufacturer part number EK-23115-000 against official Knowles documentation to ensure authenticity. Confirm that the received components match the specified rectangular package dimensions and side-port configuration. Check for RoHS compliance markings as indicated in standard product listings. Ensure storage conditions maintain component integrity prior to soldering.

Microphones Selection Notes

Select this component when an omnidirectional analog microphone is required for small form-factor applications. The -52.5 dB sensitivity rating suits general voice pickup scenarios. Consider the side-port orientation during PCB layout to ensure unobstructed acoustic access. Verify compatibility with existing biasing circuits for electret condenser microphones.

Microphones Part Context

This microphone belongs to Knowles' portfolio of audio sensors and transducers. It serves as an alternative to other surface-mount electret microphones in similar size categories. The product line focuses on providing reliable analog audio conversion for consumer and industrial electronic devices requiring discrete microphone solutions.

Microphones Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing with other omnidirectional SMD electret microphones requires independent verification of pinout, sensitivity, and mechanical footprint compatibility.
