EK-23024-P54

Microphones Overview

The EK-23024-P54 is an omnidirectional analog condenser microphone manufactured by Knowles. It features a surface-mount device (SMD/SMT) termination type and operates at a rated voltage of 1.3 V. The component has a sensitivity of -53 dB ±2 dB @ 74 dB SPL and an impedance of 4.4 kOhms. Its frequency range extends from 100 Hz to 5.5 kHz. The physical dimensions are 5.56 mm in length, 3.98 mm in width, and 2.21 mm in depth.

Microphones Feature Summary

• Omnidirectional acoustic design for uniform sound capture
• Analog output signal processing
• Surface-mount construction for automated assembly

Microphones Applications

• Portable electronic devices requiring compact audio input
• Consumer electronics with limited board space
• Voice recognition systems

Microphones Procurement Notes

Verify the specific suffix P54 against official Knowles documentation to confirm exact sensitivity tolerance and impedance specifications. Ensure compatibility with 1.3 V operating voltage requirements. Confirm RoHS compliance status through current manufacturer datasheets before integration into final designs.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for analog audio applications. The 4.4 kOhm impedance and -53 dB sensitivity suit standard pre-amplifier interfaces. Verify that the 100 Hz to 5.5 kHz frequency response aligns with target voice band requirements.

Microphones Part Context

This part belongs to the EK/EY series of microphones from Knowles Electronics. These components are designed for high-volume consumer electronics manufacturing. The series offers various sensitivity options and package configurations to meet diverse spatial and acoustic constraints in modern portable devices.

Microphones Replacement Considerations

EK-23024-C04: Similar form factor but verify sensitivity differences (-53 dBA). EK-23028-005: Same dimensions but lower sensitivity (-57 dBA); ensure pre-amp gain can compensate.
