EK-23028-C36

Microphones Overview

The Knowles EK-23028-C36 is an omnidirectional electret condenser microphone designed for surface-mount technology (SMD/SMT) applications. It features a compact footprint measuring 5.56 mm in length, 3.98 mm in width, and 2.21 mm in depth. The device operates at an operating supply voltage of 1.3 V and exhibits a sensitivity of -57 dBA. It utilizes SMD/SMT termination style for automated assembly integration.

Microphones Feature Summary

• Omnidirectional acoustic response pattern
• Surface-mount compatible termination style
• Low profile physical dimensions

Microphones Applications

• Portable electronic audio devices
• Consumer electronics with limited board space
• Voice capture modules requiring SMD integration

Microphones Procurement Notes

Verify the specific suffix C36 against official Knowles documentation to confirm exact sensitivity and port configuration. Ensure compatibility with 1.3 V supply requirements and check for RoHS exemption status if applicable. Confirm package type and handling instructions prior to procurement.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for SMD assembly processes. The 1.3 V operating voltage and -57 dBA sensitivity define its electrical interface. Verify mechanical clearance for the 5.56 x 3.98 x 2.21 mm envelope during PCB layout.

Microphones Part Context

This part belongs to the Knowles EK/EY series of microphones. It shares dimensional characteristics with similar models like the EK-23028-005 but differs in sensitivity specifications. The series is characterized by small form factors suitable for modern portable audio hardware.

Microphones Replacement Considerations

EK-23028-005 offers identical dimensions but different sensitivity (-57 dBA vs unspecified in source for replacement comparison, though listed as -57 for EK-23028-005). Verify pinout and acoustic port alignment before substitution.
